Question

In a mixture of 126 kg of milk and water,milk and water are in the ratio 5 : 2. How much water must be added to the mixture tomake this ratio 3:2 ?​

Answer 1

Answer:

24 litres of water must be added.

Step-by-step explanation:

Amount of milk in the mixture = 5/7 × 126

= 90

Amount of water in the mixture = 2/7 × 126

= 36

Now to make the ratio 3:2, let x litres be the amount of water added.

therefore,

90/(36+x) = 3/2

180/3 = 36+x

x = 24.

hence, 24 litres of water must be added to fulfil the condition.
