SSC CGL - 14 July 2023 - Shift 4 • Quantitative Aptitude • Q60

In a mixture of 55 litres, fruit juice and water are in the ratio of 4 : 1. How much water (in litres) must be added to make the mixture ratio 2 : 1?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is 3 i.e. 11

Given that

A mixture solution of 55 litres,

The fruit juice and water are in the ratio of 4: 1

The water in the solution = (1/5) × 55 = 11 litres

The fruit juice in the solution = (4/5) × 55 = 44 litres

Water is to be added so the mixture will be 2:1

The quantity of fruit juice is same in final mixture i.e. 44 litres 

According to the question

2 units = 44 litres

1 units = 22 litres

So, the quantity of water in final mixture is 22 litres

Hence, water must be added in initial mixture = 22 - 11 = 11 litres
