A man, a woman and a boy can complete a job in 3, 4 and 12 days respectively. How many boys must assist 1 man and 1 woman to complete the job in 1/4 of a day? Choose the most appropriate option:
A) 41	B) 43	C) 31	D) 84	E) 81
(1 man + 1 woman)’s 1 day work = 1/3 + 1/4 = 7/12   Work done by 1 man and 1 women in 1/4 day = ((7/12) x (1/4)) = 7/48   Remaining work = 1 - 7/48 = 41/48   Work done by 1 boy in 1/4 day = ((1/12) x (1/4)) = 1/48   Therefore, Number of boys required = ((41/48) x 48) = 41   41NSWER:41
