Question

the ratio of the milk is water in a jar is 5:2. how much pure water must be added in the jar so that the new ratio of the milk is to water is 3:2

​

Answer 1

Explanation:

Given,

Ratio of the milk in water in a jar = 5 : 2

To find ?

Ratio of the pure water to be added in the jar so that the new ratio of the milk is to water is 3 :2

Let the quantity of pure water added to the jar to gain the new ratio be 'x'.

$\frac{5}{2} + x = \frac{3}{2} \\ = > x = \frac{3}{2} - \frac{5}{2} \\ = > x = \frac{3 - 5}{2} \\ = > x = \frac{ - 2}{2} = - 1$
