Wipro Company Numerical Ability Time and Work

3 men and 5 women can complete a work in 12 days, which 5 men and 12 women can complete in 6 days. In how many days can 4 men and 4 women complete the same work?

Read Solution (Total 4)

(3m+5w)'s one day's work=1/12...1
(5m+12w)'s one day's work=1/6..2
2*eq(1)
6m+10w=1/6
6m+10w=5m+12w (from eq(2))
m=2w
so,m=2/(12*11)
w=1/(12*11)
4m+4w=1/11
ans:11

3m+5w=12 days...............>36m+60w=1 work (i) (hint: mens*days =work)

5m+12w=6 days..............>30m+72w=1 work (ii)

from 1 and 2

36m+60w = 30m+72w bcz both efficiencies are same

6m = 12w

1m=2w

from (i) 3(2w)+5w=12

11w can do the wrk in 12 days

1 women work =12*11=132

we have to find out 4m+4w =?

4(2w)+4w=12w

1w work =132

12w work = 132/12=12 days

sorry i made mistake

132/12 = 11days

3m + 5w = 12days = 5m + 12w = 6days
36m + 60w =1day = 30m + 72w = 1day
36m-30m = 72w-60w
6m = 12w
1m = 2w
4m*2+4w = 12w.
3m*2+5 = 11w
M1D1 = M2D2
11*12 = 12*?
11days

Wipro Other Question

P and Q agreed to complete a job in 15 days for $6200. P can complete the same job in 50 days and Q in 30 days. They had to take R to complete the work in time. Find R's share in the money earned by them. A is 80 % more efficient than B who is 60% more efficient than C. A takes 40 days less than B to complete a work. A starts the work and works for 25 days and then B takes over. B then work for the next 30 days and then stops. In how much more time can C complete the remaining work?
