Hexaware Company Numerical Ability Time and Work

Two men and three women working 7 hours a day finish a work in 5 days. Four men and four women working 3 hours a day complete the work in 7 days. The number of days in which only 7 men working 4 hours a day will finish the work is?
A)10 B)5 C)7 D)6

Read Solution (Total 2)

2m+3w=1/(7*5)
4m+6w=1/(3*7)
On solving
m=1/140
W=1/210
7m=1/(4*X)
7(1/140)=1/4x
1/20=1/4x
Then X=5
