Question

A mixture of 40 liters contains wine and water in the ratio of 3:1. How much water must be added to the mixture so that the ratio of wine and water is 5:2 ?

• A. 4 lts
• B. 3 lts
• C. 2 lts
• D. 5 lts

Answer 1

The correct option is C 2 lts

solution:

in 40 litres of mixture 30 litres are wine and 10-litre water.

let we add x litre of water so the ratio becomes 5:2

the wine remains the same so

$wine:water$

3 : 1 x 5

5 : 2 x 3

15 : 5

15 : 6

15+ 5 = 20 so to make 40 liter

1 unit = 2 liter

there is 1 unit change from 5 to 6 means 2 liter is added

hence the correct option:C
