Question

A piece of work can be done by 8 men or
12 boys in 20 days. How long will it be
taken by 6 men and 6 boys to complete
the work ?​

Answer 1

Answer:

16 days

Step-by-step explanation:

8 Men = 12 Boys

Man/Boy = 3/2

6 Men = 3/2 * 6 = 9 boys

so in total 9+6 = 15 boys are working

12 boys take 20 days, so 15 boys will take 16 days
