14 men can complete a work in 12 days. 4 days after they started the work, 2 more men joined them. How many days will they take to complete the remaining work ?
-
- 9 days
- 5 days
- 6 days
- 7 days
Correct Option: D
∵ In 12 days work done by 14 men = 1
∴ In 4 days work done by 14 men = 1 x 4/12 = 1/3
∴ Remaining work = 1 - 1/3 = 2/3
and number of total men = 14 + 2 = 16
If 1 work is done by 14 men in 12 days
∴ 2/3 work is done by 16 men in 12 x (14/16) x (2/3) = 7 days
