Correct Answer: $2\frac{8}{11}$
Solution : 10 women can do work in 6 days Work rate of 1 woman = $\frac{1}{60}$ 6 men can do the same work in 5 days Work rate of 1 man = $\frac{1}{30}$ Combined work rate = (10 women's work rate) + (6 men's work rate) $= \frac{1}{6} + \frac{1}{5} = \frac{5+6}{30} = \frac{11}{30}$ Now $\frac{11}{30} d = 1$ $\therefore$ $d = \frac{30}{11}=2\frac{8}{11}$ days Hence, the correct answer is $2\frac{8}{11}$.
