24 persons can do a piece of work in 20 days. In how many days can 30 persons do the same work?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 16

Total work = No. of Persons × Days 

Total work = 24 × 20 

The total number of days taken by 30 persons = (24×20)30\frac{(24 × 20)}{30} = 16 

The required number of days = 16
