Question

If 12 men or 20 women can do a piece of work in 54 days, then in how many days can 9 men and 12 women together do the work?

Answer 1

Given,

12 men or 20 women can do a piece of work in 54 days

To find,

The number of days that 9 men and 12 women will take to do the same work.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Here, we have to apply the normal arithmetic method.

12 men 20 women can finish in = 54 days

1 man 1 woman can finish in = 54×12×20 days

9 men 12 women can finish in = (54×12×10)/(9×12) = 60 days

Hence, they will finish the work in 60 days.
