SSC CHSL - 3rd July 2019 - Shift 3 • Quantitative Aptitude • Q75

18 men can complete a work in 9 days. After they have worked for 5 days, 6 more men join them. How many days will they take to complete the remaining work?

Show answer & explanation

Correct answer: D

Explanation

Correct Answer is option 4 i.e. 3

Understanding

Application

Since 18 men can complete a work in 9 days:

Total work = 18 × 9 = 162 units 

Since 18 men have worked for 5 days:

Remaining work = 162 – 18 × 5 = 72 units

Number of men after 5 days = 18 + 6 = 24

Hence,

Time in which remaining work will be completed = 72/24 = 3 days
