The ratio of efficiences of a man and a woman is 3 : 2. If 15 men take 24 days to complete a work, working 12 hrs a day, how much time will 18 women take to complete the same work working 10 hrs a day?
Answer & explanation
Correct answer: option 4
M x Eff. x Hrs. x Days = constant (when work is same)
15 x 3 x 12 x 24 = 18 x 2 x 10 x No. of days
No. of days = 36 days
