On adding 24 litres of water,

72x

= (

⇒

25

= 24
⇒ x =

24×25

12

= 50
∴ Initial quantity of mixture= 4x
= 4 × 50 = 200 litres
OR
Let initial quantity of mixture= 25 litre
In 24 litres,
Milk = 18 litres
Water = 6 litres
When,3 litres water is added,
Milk : Water = 2 : 1
∴ If 3 litres of water is added total mixture = 25 litre
∴ If 24 litres of water is added total quantity =

25×24

= 200 litres
