Question

8 men or 12 boys can do a work in 50 days.in how many days 6 men and 11 boys can do it.

Answer 1

Step-by-step explanation:

8 men complete in 50 days so 1 men can complete in 8 * 50 = 400 days

12 boys can complete in 50 days so 1 boy can complete in 12*50 = 600 days

in one day 1 men can complete = 1/400 part

6 men can complete = 6/400

in 1 day 1 boy can complete = 1/600

part

11 boys can complete = 11/600

total work completed in one day

6/400 + 11 / 600

(18+22)/1200 = 40/1200 = 1/30

so the whole work can be completed in 30 days
