Explanation

We know: 10 men + 5 women complete the work in 12 days. Also: 8 children complete the same work in 16 days. We need to find: 3 men + 2 women + 2 children's rate. However, we have no information about the relative efficiency of men vs women vs children. Without knowing how a man's work compares to a woman's or a child's, we cannot combine these rates. The data is insufficient.
