Q:

Twelve children take sixteen days to complete a work which can be completed by 8 adults in 12 days. After working for 3 days, sixteen adults left and six adults and four children joined them. How many days will they take to complete the remaining work ?

A) 3 days B) 2 days
C) 6 days D) 12 days
 
Answer & Explanation Answer: C) 6 days

Explanation:

From the given data,

12 children 16 days work,
One child’s one day work = 1/192.


8 adults 12 days work,
One adult’s one day’s work = 1/96.


Work done in 3 days = ((1/96) x 16 x 3) = 1/2


Remaining work = 1 – 1/2 = 1/2


(6 adults+ 4 children)’s 1 day’s work = 6/96 + 4/192 = 1/12

1/12 work is done by them in 1 day.

1/2 work is done by them in 12 x (1/2) = 6 days.
