Correct Answer

Explanation

The work rate of one woman is 1/70 of the task per day,
and the work rate of one child is 1/140 of the task per day.
The combined work rate of 5 women and 10 children is (5/70 + 10/140) of the task per day,
which is equal to 1/14 of the task per day.
Therefore, it will take 5 women and 10 children a total of 7 days to complete the task
