12 women and 16 men can do a piece of work in 11 days. If each woman takes twice the time taken by a man to do the work, in how many days will 16 men do the same work?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (121/8) days.
The ratio of the efficiency of Man and Woman = 2 : 1
Total work = [(12 × 1) + (16 × 2)] × 11 = 44 × 11
So, 16 men can do the same work = (44 × 11)/(16 × 2) = 121/8 days
