Answer : 1. "4 days"
Explanation :

Answer: A) 4 days Explanation: Given that  6 men and 8 boys can do a piece of work in 10 days  26 men and 48 boys can do the same in 2 days   As the work done is equal, 10(6M + 8B) = 2(26M + 48B) 60M + 80B = 52M + 96B => M = 2B => B = M/2 ……(1)   Now Put (1) in 15M + 20B => 15M + 10M = 25M Now, 6M + 8B in 10 days => (6M + 4M) 10 = 100M Then D(25M) = 100M => D = 4 days.
