Question

12 men complete a work in 9 days. After they have worked for 6 days, 6 more men joined them. How many days will they take to complete the remaining work? Select one: a. 5days b. 2 days c. 4 days d. 3 days

Answer 1

Correct Answer = 2 days

Explanation:

12 men worked for 9 days = 12 * 9 = 108

after working for 6 days = 12 *6 = 72

days left = 108 - 72 = 36

6 more men joined = 12 + 6 = 18

so, no. of days taken = 36 / 18 = 2 days
