Given,
10 women can finish the work in 7days
& 10 children take 14 days to complete same work.

Work done by women per day= $\frac{1}{70}$

Work done by child per day= $\frac{1}{140}$

Part of work done by 5 women & 10 children per day

= $\frac{5}{70} + \frac{10}{140}$

= $\frac{10}{140} + \frac{10}{140}$

= $\frac{20}{140}$

= $\frac{1}{7}$

•°• 5 women and 10 children take 7 days to complete the work.
