Answer:
Option (a) is correct.
Step-by-step explanation:
In the newly formed mixture,
Quantity of milk = 48 litres
Quantity of water = 12 litres
The ratio of milk and water in newly
formed mixture is 48:12
That is 4:1
When 12 litres of newly formed mixture is taken out,
quantity of milk remaining in the jar is 48 litres.
The quantity of milk left in the jar
= (4/5)th of quantity of newly formed mixture
= (4/5) × 48
= 0.8 × 48
= 38.4 litres
