Q: 12 men complete a work in 14 days. 5 days after they had started working, 3 men join them. How many more days will all of them take to complete the remaining work?

Let p be the required number of days. From the given data, 12 x 14 = 12 x 5 + (12+3) x p 12 x 14 = 12[5 + 3p] 14 = 5 + 3p 3p = 9 p = 3 days. Hence, more 3 days all of them take to complete the remaining work.

Correct Answer: 3

Explanation:

Let p be the required number of days.

From the given data,

12 x 14 = 12 x 5 + (12+3) x p

12 x 14 = 12[5 + 3p]

14 = 5 + 3p

3p = 9

p = 3 days.

Hence, more 3 days all of them take to complete the remaining work.
