A man can finish a work in 10 days and a woman can finish it in 12 days. In how many days will the work be finished by a man and a woman, working together every day?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. .
We know that,
Total work = Number of days × Efficiency
Now, according to the question
Work done by a man in one day = 1/10
Work done by a woman in one day = 1/12
Working together = 1/10 + 1/12 = 11/60
They will together complete the work = 60/11 days
