Question

if 10 men can do a piece of work in 20 days how long will it take 8 men to do the job if they work at the same rate?

Answer 1

Obviously we can’t solve this problem by usual method of unitary ...
Time taken by 10 me to do the work= 20 day
Then time taken by 1 man to do the same work = 20 x 10 (*and not 20/10,as per the rules of mathematics.....how the hell ca single man can do the same work in just 2 days.....??!!!??....therefore we multiplied it)

So time taken to do the work by a man = 20 x 10= 200 DAYYYSSS..!

THEREFORE TIME TAKEN BY 8 MEN TO DO THE WORK= 200/8 ( yeah....more people would do the work in less days....uhh please ignore my Eng)

Hence time taken by 8 men= 200/8 =25 daysss....

25 days is ur ans
