thirty okay so the difference average difference number by plus last number by two first number in the six plus thirty by two thirty six by two so 1890 so 18 is 6 plus 12 plus 18 plus 24 plus 30 by 5. average of first to five multiples of six first n multiple equal to n plus one multiple n plus one multiple by two n plus 1 to multiple by two so five multiplier in so um multiple of 6 by 2 36 6 36 so 36 by 2 in the answer 80. average students next the average of first 11 multiples of 5 and first 11 multiples of five children is the average of first in multiple and day n plus one multiple by two formula so first eleven under one n plus one multiple in 12th multiple of five twelfth multiple of 12 to multiple of 5 and the 60. so 60 by 2 equal to 30 average Infinity foreign 25 30 35 40 45 50. fifty five sixteen one two three four five six seven eight nine 10 11 12 multiply together twelfth multiple of five by average Thirty is next the average of first to 15 multiples of 12. children so formulas average of first to 15 multiple so 16th multiple n plus one gravity 16th multiple of 12 by 2 hours so 16 into 12 and 192. 192 by 2 so 2 9 18 2 6 so 96 and average next the average of first to 10 prime numbers first 10 prime numbers [Music] two three five seven eleven thirteen Seventeen nineteen uh 23 29. 2235 79 um thirteen fifteen Seventeen nineteen twenty two Twenty One guys and the first number plus last number by two usually when you play challenge [Music] next the average of prime numbers between 7 to 29 7 to 29 any prime minister trend um so eleven thirteen there was a seventeen twenty one twenty three so Indiana one two three four five so seven to twenty six monthly um 25 other 27 325 both only twenty seven more than 29 uh foreign sum of observations by sum of observation by number of observations so up to 11 plus 13 plus 17 plus 19 plus 23 by 1 2 3 4 5 5. okay eventually thirteen plus Seventeen twenty eight thirty Thirty hours foreign foreign between another um seven eleven thirteen Seventeen nineteen twenty three including yes sum of observations by number of observations some more of observations by number of observations legendary 7 plus 11 plus 13 plus 17 plus 19 plus 23 plus 29 bye yesterday Seven Wonders so seven sevens are 49. so zero so answering Seventeen and average from this column between gravity 16.60 okay but next question type model questions next the average of nine consecutive the average of nine consecutive natural numbers is 83 and okay find the find the largest number is so first 83 middle number into foreign okay continue to numbers one two three four uh one two three four five one two three four five one plus two plus three plus four plus five five plus four and the nine nine plus twelve and nine plus three hundred twelve foreign foreign one two three one two three add numbers [Music] so second smallest number is second smallest number is 51. answer either questions okay next next type of models the average of 11 numbers is 42. okay average of 11 numbers one two three four five six seven eight nine ten eleven the average of energy examples of 4200 average of level numbers if the average the first to five numbers is for data okay one two three four five foreign foreign um okay children name is okay so eleven numbers 42 average so first to five numbers average 200 or something last five numbers average and instead of 43 43 43 5000 250 now um uh 200 plus foreign middle number is first five numbers into forty so five into forty two hundred five into four five two fifteen five five ten eleven uh foreign foreign additional okay input is 43 number three last five numbers minus minus 5 okay so print out in the Japanese seven okay seven is minus five and sorry 1842 42 plus 10 uh 42 plus 10 and 30 52 52 minus 5 and D in Thousand Japan 47 so answer forty seven average shortcut followers any numbers are the five numbers so 5 into 210 additions next the average of 11 numbers is 42 22 numbers okay sorry the average of 22 numbers is uh that there are 22 numbers average is 40 dollar so there are 22 numbers average is 42. 20. there are 22 numbers average is 42 22 numbers okay the average of first to ten numbers in the average 39. last and level number Center 462 find the missing number or not 22 numbers average 52 each other faster 10 numbers average 39 each other last 11 numbers the average of 46 each other missing number one call okay 42s is Less in any number see ten ten numbers okay 10 numbers so thirty three into ten foreign foreign [Music] foreign [Music] into uh okay next same type of model questions next the average marks of 25 students in the class is 480 and okay average marks of 25 students 48 right the average marks off 25 25 students so enter 48 each other it was found that while calculating the average of one voice marks who got a 580 was wrongly taken as 380. right there find the correct average 25 students the average student 25 student average 480 380 foreign foreign shouldn't say um foreign foreign by [Music] foreign [Music] next foreign while calculating the average later on it was found that while calculating the average one reading is 147 centimeter wrongly taken as 177 centimeter why find the correct average 15 students average 159 centimeter only students yeah ending up by the 140 147 centimeters average foreign [Music] foreign minus 177 minus 147 by 15. average property total average 159 minus um by 15. so 15 ones are fifteen twos are so 159 minus 2 so in third answer 157 centimeter okay types of model questions 159 minus one 177 minus 147 byte average 15 members minus Thirty by fifteen fifteen one the 15th so 159 minus two so 157 centimeter average corrected average questions foreign foreign okay next suppose from the values we can find find out the ratio 18 is to 24 Richard Hamilton is only three is to foreign next so inverse test four inverse direct to four is to 3 equal to answer directive inverse gravity foreign foreign foreign India um foreign foreign conduction next find the ratio of foreign eight eight three levels four threes are 12 3 12. three fours are twelve four into two so three into one is two six into three and yeah foreign so duplicate find the duplicate ratio of and something else duplicate duplicate and take square of a given number until the ratio numbers children name duplicate square numbers so square of a given number square of a given number duplicate next sub duplicate square root of a given number square root of a given number and people suppose examples already 16 is to 90 square root foreign foreign next to the money sub replicate cube root of a given number given number 27 is a duplicated square of a given number sub duplicate and square root of a given number triplicate into cube of a given number subscribe and then it is next find the duplicate ratio for uh okay find the duplicate ratio of nine is to 400 duplicate ratio duplicate ratio duplicate ratio square root of a sorry nothing duplicate iteration duplicate ratio square of a given number okay 9 is to 4 Randy foreign find the sub duplicate ratio of 9 is to 4 and okay find the sub duplicate ratio of 9 is to 4 sub duplicate duplicating square root of a given number chemical number nine is to foreign foreign number cube of a given number two of a given number okay foreign 5 is to 900 subscribe into five into five so seven thousand is 125 awesome nine inch nine into nine into nine interestingly 729 cubes let's put about foreign number okay so cube root of a given number in so my name is 27 66 36 36 6216 internet is simple foreign square of a given number okay so my chemical numbers 25 children 16 25 so 16 square Infinity 625 256 625 squares one two points together foreign foreign foreign find the ratio of 1 by 4 is 2 2 by 3 is to three by two damage foreign indexable interest is next if a is to B is 2 is to 3 B is to C 4 is to Phi find a is to B is to see 11 questions examples okay foreign foreign evil is it two foreign internet foreign okay so multiplayer into answer in tenant okay next question sorry a is to be equal to is foreign foreign foreign foreign foreign foreign [Music] foreign okay next the sales sorry the salaries of Shruti Puja sushma the salaries over two is two threes to five ND then what will be the new ratio of their salaries questions foreign foreign 100 . ten percent of 330. next 20 percent of 500. Japan ten percent and fifty you put 10 percent into fifty so hundred and just fifteen percent of 200 in the Thirteen plus thirty adding two hundred legendary 230 300 plus uh Thirty in the three thirty five hundred plus hundred and six hundred numbers simple learning okay next question foreign ratio three is to five find the bigger number find the bigger number okay one is to two three is to five ask only five ideas foreign foreign [Music] difference equal to one difference okay two different equivalent two difference so new day two is to four three is to 5. foreign one is to two each other please to find Shadow so you can differences foreign foreign foreign foreign rupees so find the number of five rupees come um find the number of five rupees numbers okay okay so 25 Paisa okay two is two either three is twenty so we put 25 pesos 25 percent 0.25 0.10 0.05 foreign watching [Music] ratio Financial foreign foreign three parts so three percent okay so you cancel the estimate again three into Thirty by well if you cancel this is 7.5 years so it's a 1.5 rupees five rupees find the number of five rupees 7.5 amount so I'm gonna do five rupees five pieces bye girl 150 and 150 coins 155 foreign five Paisa coins okay okay next simply next the ratio of two numbers the ratio of two numbers is one is to find ratio of two numbers is ratio of two numbers one is to 5. 320. then find the largest number then look at the numbers so the ratio of two numbers is one is to five and their product is 320 then find the largest number is okay if you wanted okay let it okay one x five x product Number One X Y so then in ratio ratio of two numbers so next time so 5X Square equal to 320. foreign [Music] Japanese internet okay a smaller number and ten times the ratio of two numbers is the ratio of two numbers is 2 is to three and E the ratio of two numbers is two is to 3 2 3.50 foreign x x square equal to 9 gravity of x equal to under root nine over takes equal to 3 out so x equals three into three so values to find the numbers numbers okay next foreign folder scholarships okay scholarships [Music] scholarship rather and a scholarship foreign foreign foreign foreign currency folder foreign 200 it is zero it is zero okay so 5 399 35 so answering that 78 percentage three ninety by five Json 78 percentage scholarships 78 percentage okay so first it's our total number of girls and boys so um welcome to python life previously manam ratio same proportions first time and work time keep working mother relations first time and work okay so time T is directly proportional to work foreign foreign [Music] foreign [Music] work ER directly proportional to work and then foreign more more men do more work and less men do less work and yes men is inversely proportional time many times yes more men do working less time is ready um foreign enough more men do work in less time less men take more time to complete the work to complete the work s inversely proportional to time directly proportions multiplications foreign then A and B completed the work in how many days questions then A and B completed the work in how many days foreign foreign another okay 30 days LCM this is deficiency 3260 and the efficiency three parts dailymary foreign total worker 60 percent is not three parts efficiency three parts is two parts okay okay in the Japanese is sixty by five days class multiplication uh students then A and B complete the work in how many days yesterday so 60 Parts sixty percentage sorry 12 days foreign Monday product to buy some um two people involved two people involved I know conditions are given then we use this shortcut shortcut in the product to buy some foreign foreign foreign so in how many days all of them together can do the work A and B 12 resolution so a plus b plus c d c plus d and they are gals in Hindi a place foreign C plus d four days low competition or work so fast a plus b plus C plus d equal to Total Works or twelve so LCM 12 hours foreign so foreign foreign okay um foreign [Music] Japanese product 12 into 4 12 plus 4. 12 into 4 plus 16 so 4 3 is a four for the four one the four ones are four four canceling the four four cancellation so answering my three days next foreign foreign product by different Sunday products by difference by difference so product 10 20 20 into 15 and a bye difference in the 20 minus 15. 20 into 15 by 5 5 1 0 5 3 so ammo in the answer 60 days this logic work for only two people product by Sum productive by difference next working together can complete a task in eight day Sunday foreign take to complete the task so one any day this is foreign shoot them product 8 into 12 12 minus eight eight into 12. 4 12.8 into 12 by four four one the four to the so operation 2 into 12 so 24 days Suman Suman will complete the task in 24 days and same questions any question okay next next question can complete the work in 20 days and Shruti can complete the work in 20 days Puja can complete the work in 15 day Sunday children then sushma can complete the work in 30 days then Shruti Puja and sushma can complete the work in how many days should recommendations foreign okay foreign [Music] foreign foreign next in the um sushma one day low any parts company 73 plus 4 plus 2 in 30 nine parts nine Parts name one day completely essay nine percent sixty Parts yesterday independent Japanese six two by three days foreign foreign [Music] B can compare the work in 15 days a day so a plus b plus C together can complete the work in five day Sunday so alone can complete the work in how many days product by difference okay 20 days 15 days 20 day Sunday 15 day Sunday a plus b plus c in the five days foreign total work total working thousand depending 2015 5.20 so 21 the 20 22s are forty four fifty levels so 23 to 60 60 and days 23 efficiency 15 for the 5 12 so if efficiency Sunday efficiency okay okay three efficiency four efficiency 12 efficiency B can compare the work 15 days foreign so seven parts seven Parts in one day now efficiency a plus b plus C twelve percentage Yeah a plus b plus c equal to 12 right there c equal to 12 minus a plus 12 minus a plus b and ten times okay seven substitutions foreign simple yes teacher is foreign can complete the work in 25 days 30 days and 50 days respectively foreign gets completed Randy yeah if they work in cycle ABC is foreign uh um foreign foreign one day fourteen Parts in three days three days so 14 Parts 14 Parts in three days then to multiply yesterday 1410 140 14 11 for the 44 11 uh 154. [Music] 140 so um foreign turandoxide 1410 140 foreign foreign foreign foreign next is next to one any any person different efficiency five parts yesterday so 150 Parts 146 key foreign so answer is 31 by 31 4 by 5 days 14 Parts in three days three days 14 parts 14 percent three days so 140 Parts in 30 days 146 Parts in 31 days foreign foreign foreign okay 14 140 Parts in 30 days 25 B13 C 50 days efficiency already okay series 143 31 days foreign foreign next okay yeah foreign starting with b another starting with uh so starting with foreign foreign [Music] foreign foreign [Music] 20 days 110 parting parsing 20 day Sunday so you put Angels starting with b another three parts be efficient in the three parts so one one three parts in 21 days one day low three parts one one three parts in 21 days next year yeah um 120 parts 21 7 by 8 days answer internet 21 7 by 8 days since seven days three parts so 21 days next during the day foreign foreign foreign a plus b uh 12 days B plus C 15 days yes foreign 12 into 15 next B C 15 to 20 plus 20 into 12 and so I'm gonna give any multiply yesterday 180 plus uh 300 plus 240 seven two double zero seven two double zero 180 Plus 300 plus 240 8 000 Japanese so 10 days foreign directly proportional directly proportional men is directly proportional to work many is directly proportional to work on Japan is directly proportional to work many is directly proportionately cross multiplication proportional time is inversely proportional to Menon our main is inverse the proportional time on Elantra Time Low direct uh suppose in 10 days two men in 20 days multiplication proportional time and AMD men straight multiplications foreign [Music] foreign foreign recognition M1 D1 equal to m 2 D2 okay okay foreign [Music] work time and work directly work and time directly proportional gravity as in class multiplication M2 D2 H2 by work one work two foreign directly proportional to work multiplication Sunday menu Min is inversely proportional to time gravity direct multiplication day and hours and time gravity direct multiplication is directly proportional to work directive proportional potential cross multiplication by W1 equal to equal by W2 is 14 minutes 14 men complete the work in 18 day Sunday 21 Min are implied then the time required to complete the same work will be either regards many times inversely proportional time okay so um D2 14 main competitive working 18 days [Music] D2 days three D2 equal to 12 days so six into two twelve days next Inland type of income question is next 20 men complete the work in 40 days 20 men foreign for the 40 10 4 the 40 so D equals D2 equal to 20 into 4 d 2 equal to e80 days foreign [Music] foreign H1 okay M1 D1 equal to h1a Second formula is foreign okay five hours daily eh 2. daily five years five years daily companies five hours daily work which is 40 days any days M1 D1 H1 equal to M2 D2 is 2. time is inversely proportionality okay D1 and H1 and M2 enter 1090 um five hours each other okay friend over five years okay five years so if I if I cancel it so ten fourth and 40 so D two equal to 80 day Sunday 20 minutes daily five hours completely 40 days foreign it is given that 16 men working 18 hours per day can build a wall 16 Min 18 hours per day 18 hours 16 men working 18 hours per day to build can build a lamp Builders 36 meter long 4 meter abroad 24 meter height in 20 days 16 minutes 18 hours per day Destiny work um 36 meter long 4 meter broad 24 meter Heights slow [Music] foreign foreign 16 days low subscribe foreign first two 1690 s 36 into 4 into 24 Okay so foreign foreign next foreign six Wonder six for the okay foreign foreign foreign soldiers thousand soldiers yes okay in a Garrison there was food for the Thousand soldiers for the month of June June month of June after 10 days 30 days 30 days okay after 10 days 10 days after 10 days 1000 more soldiers giant The Garrison thousand more soldiers China thousand more soldiers after ten days thousand more soldiers in Garrison how long would the soldier be able to carry on with the remaining food so mundu thousands foreign okay 10. 10 days foreign foreign next question a person was appointed for 50 days fifty days condition condition that he we he will be paid 12 for every working day rupees 12. working day 12 rupees working day um but he will be fined six rupees for every day he remains upset option 26 rupees foreign foreign working day um foreign foreign so four is to 1 is a person was appointed for 50 days total in the 50 days 50 days gravity five parts fifty days money 10 into 6 60 rupees 60 rupees minus 50 days foreign foreign star mark y topics foreign s t okay efficiency so efficiency one is to two times questions efficiency is inversely proportional times okay a can do efficiency a can do three times faster than b yeah three times faster than b another three times faster than b okay therefore takes 40 days less than b what it is foreign foreign one into fourteenth of 40 days 40 days 2 into 20. 2 into 20 hours and 20 days 20 days be three parts 60 days okay so differences Equalization so two into twentieth of forty align one into twenty twenty B and number three into twenty six days foreign foreign foreign eighteen thousand five RT find the wages efficiency is inversely proportional to time Monday efficiency is inversely proportional to time okay efficiency is inversely proportionality efficiency foreign foreign foreign foreign foreign so thank you for watching this video Andy if you like our content please subscribe to python Life channel and
