20 litre of mixture contain milk and water in the ratio 5 : 3 . If 4 litre of the mixture are replaced by 4 litre of milk, the ratio of milk to water in the new mixture will become

Answered by admin @ 20/08/2021

Heya !!

==================================

Given that, 20 litres of mixture contains milk and water.

Ratio of water = 5 : 3 and milk = 5/8

Now, 4 litre of mixture is replaced by milk.

So, total mixture available = 20 – 4 = 16 litres

Quantity of milk in 16 litres mixture = 16 × 5/8

=> 2 × 5

=> 10 litres

Quantity of milk in 20 litres new mix. = ( 20 + 4 )

=> 24 litres

Quantity of water in mix. = ( 20–14 )

=> 6 litres

Thus, ratio of milk and water in the new mix. = 14 : 6 = 7 : 3
