Question

30 men and 20 women can complete a piece of work in 20 days after working for 5 days all the women left the work the remaining work was completed by those 30 men in 90 days in how many days can 20 women finish the entire work

Answer 1

Answer:

180 days

Step-by-step explanation:

Given,

30 men(m) and 20 women(w) can complete a piece of work in 20 days

30m+20w=1/20

after working for 5 days =5/20=1/4 days worked

remaining work 1-1/4=3/4

let the total work is 4p

and 3p work completed by 30men in 90 days

we know,

work=men*days*hours

3p=30m*90days      -----(1)

in how many days can 20 women finish the entire work 4p

4p=20w+x days      -----(2)

dividing Eq(1) by (2)

3p/4p=30*90/20*x

x=180 days
