Question

If 10 men or 12 boys can finish a work in 44 days, how long will 20 men and 6 boys take to
finish the work ?​

Answer 1

Answer:3 men = 6 boys

4 men =   x 4 = 8

Total boys in second case :

= 4 men + 12 boys = 8 + 12 = 20 boys

6 boys can do a piece of work in 20 days

Then let 20 boys will do the same work in x days

∴ 6 : 20 :: 20 : x

(More boys, less days)

⇒ 6 : 20 :: x : 20

(By inverse proportion)

X = (20 × 6)/20

= 6 days

∴ They will do the work in 6 days
