Answer 2

Answer:

The Answer is 36 days

12 men complete the work in 72 Days

30 Boys complete the work in 72 Days

By equating Men and Women

12 Men x 72 Days = 30 Boys x 72 Days

By resolving the above equation we get

1 Man = 1.5 Boys or 30 Boys = 12 Men

12 men complete the work in 72 Days

(12 men + 30 Boys ) or ( 12 M+ 12 Men = ) 24 Men can complete the work in HOW many Days ?

It will be Less days

Let us use School formula

Then the equation will be (LESS / MORE) x 72 Days

The equation will be ( 12 / 24 ) x 72 days = 36 Days

24 Men can complete the work in 36 Days
