106. One man, 3 women and 4 boys can do a piece of work in 96 hours, 2 men and 8 boys can do it in 80 hours, 2 men & 3 women can do it in 120 hours. 5 Men & 12 boys can do it in how many hours?
Answer: 43 7/11 days
Explanation:Lets assume man, women and boy as M, W, B respectively.
So, m+3W+4B=1/96 ------- (1)
2M+8B=1/80 -------- (2)
2M+3W=1/120 ---------(3)
By solving above eq.
4M+16B=1/40 4
eq(3)+eq(4)
5M+12B+(M+3W+4B) = 1/40+1/120
5M+12B=11/480 = 43 7/11 hrs.
