4 women or 6 boys can finish a work in the same number of days. A boy can finish it in 60 days. In how many days can 5 women finish the work, working together every day?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 8
Let the efficiency of a women be w and the efficiency of a boy be b
Given that
4 women or 6 boys can finish a work in the same number of days
According to the question
4 w = 6 b
w/b = 6/4 = 3/2
If A boy can finish it in 60 days,
Total work = 60 × 2 = 120
Hence, 5 women complete this work in = 120/(5 × 3) = 120/15 = 8 days
