A) 5 days
B) 15 days
C) 28 days
D) 6 days
Correct Answer: D
Solution :
Work done by 10 men, 4 women and 10 children together in 1 day \[=\frac{10}{8\times 12}+\frac{4}{4\times 48}+\frac{10}{10\times 24}\] \[=\frac{5}{48}+\frac{1}{48}+\frac{1}{24}\] \[=\frac{8}{48}=\frac{1}{6}\] Hence, required time = 6 days.
