Wipro Company Numerical Ability Time and Work

4 men or 5 women can construct a wall in 82 days.How long will it take 5 men and 4 women to do the same?

Read Solution (Total 4)

40 days ans.
A man's 1day work =1/82*4
An woman's 1day work=1/82*5
so,(5men+4women)'s 1day work=(5/82*4)+(4/82*5)=1/40
hence,they can complete the same work in 40days.

40 days

5 men and 4 women = 5+ 4*4/5 = 5+16/5 = 41/5 men

4 men or 5 women can construct a wall in 82 days.
4 men can construct a wall in 82 days.
41/5 men can construct a wall in 82 *4*5/41 = 40 days .

Here, 4men = 82days so,
1men = 1/82*4.....(1)
similarly 1 woman = 1/82*5...(2)
now putting values of 1 & 2 in equation..
5men+4 women = 5(1/82*54+4(1/82*5)
we get... 40 days..

Wipro Other Question

If 9 men and 12 boys can do a piece of work in 4 days and 4 men and 16 boys can do the same piece of work in 6 days. How long will 6 men and 24 boys take to complete the same work? To do a certain work C alone takes twice as long as A and B together. A would take 3 times as long as B and C together. All three together complete the work in 5 days. How long would each take separately?
