10 men and 8 women can together complete a work in 5 days. Work done by a woman is equal to the half of the work done by a man. In how many days, will 4 men and 6 women complete that work?
A) 12 days
B) 10 days
C) \( \Large 8\frac{2}{3} \) days
D) \( \Large 9\frac{3}{4} \) days
Correct answer:
B) 10 days
Description for Correct answer:
1 man = 2 women
10 men + 8 women = 20 women + 8 women = 28 women
4 men + 6 women = 8 women + 6 women = 14 women
Because, 28 women do the work in 5 days.
Therefore, 1 woman can do the same work in days.
Therefore, 14 women will do the same work in \( \Large 28 \times 5 \) days
Therefore, Required number of days = \( \Large \left(\frac{28 \times 5}{14}\right) = 2 \times 5 \) = 10
