Question

1 man and 5 women are able to complete a piece
of work in 20 days. Same amount of work is
completed by 4 men in 8 days. Find the number of
days required by 5 men and 1 woman to complete
the same work.​

Answer 1

Answer:

6.25

Step-by-step explanation:

(1M+5W)*20=4M*8

on solving it we get,

25W=3M

or 1W=3/25M

we can write the problem as:

(5M+1W)*x_days=1

replacing W by M

(5M+3/25M)*x_days=1

Equate this with any of the known work

(5M+3/25M)*x_days=4M*8

x=6.25
