Correct Answer: 16


Solution : Let the efficiency of a woman, a man, and a boy be w, m, and b, respectively.
According to the question,
4m = 6w and 4w = 6b
Let b = 4 units per day, then w = 6 units per day, and m = 9 units per day.
Now, total work = 4 × 60 = 240 units
One day work of 1 man and 1 woman = 9 + 6 = 15 units
So, the time taken by 1 man and 1 woman to complete the work = $\frac{240}{15}=16$ days
Hence, the correct answer is 16.
