Question

.If 5 men can do a work in 2 days and 3 boys can do the same work in 5 days, then find the time taken to complete same work by 10 men and 3 boys.

Answer 1

Answer:

12.5 days

Step-by-step explanation:

Here I will use the concept of

Man*Days

(2m+3b) 10 = (3m+2b) 8

20m+30b = 24m+16b

14b = 4m

7b = 2m

So 2m = 7b

Now

(2m+3b) 10 = (2m+1b) x

(7b+3b) 10 = (7b+1b) x

10*10 = 8*x

X = 100/8

X = 12.5 days
