Question

1 man,1 woman and 1 boy together can ginish a work jn 5 days.But 5 woman and 5 boys can do 7/12th of the work in 1 day​

Answer 1

Answer:

1 man + 1 woman + 1 boy can finish work in 5 days

1 woman can finish work in 10 days

1 boy can finish work in 16 days

Calculation:

Let the time taken by 1 man be ‘x’ days.

⇒ (1/x) + (1/10) + (1/16) = 1/5

⇒ 1/x = (1/5) – (1/10) – (1/16)

⇒ 1/x = 3/80

⇒ x = 80/3
