L&T Company Numerical Ability Time and Work

The work done by a woman in 8 hours is equal to the work done by a man in 6 hours and by a boy in 12 hours. If working 6 hours per day 9 men can complete a work in 6 days, then in how many days can 12 men, 12 women and 12 boys together finish the same working 8 hours per day?

Read Solution (Total 1)

6M=8F=12B
That is 3m=4f=6b eq-1
12m+12f+12b eq-2
1m=2b
1f=6/4b
So putting in eq-2
54b
6m*6*9=54b*d*8
12b*6*9=54b*d*8
D=3/2=1.5 days
