Option 3 : =,<
Quantity of milk in the initial mixture = 7/12 × 132 = 77 litres
Quantity of water in the initial mixture = 5/12 × 132 = 55 litres
Quantity of milk in the remaining mixture = 77 – 7/12 × 48 = 77 – 28 = 49 litres
Quantity of water in the remaining mixture = 55 – 5/12 × 48 = 55 – 20 = 35 litres
Milk = 49 + 6 = 55 litres
Water = 35 + 20 = 55 litres
Milk : Water = 55 : 55 = 1 : 1
Quantity A:
Quantity of milk left in the container = 55 – 1/2 × 42 = 55 – 21 = 34 litres
Quantity B:
Quantity of water left in the container =55 – 1/2 × 42= 55 – 21 = 34 litres
Quantity C:
35 litres.
∴ Quantity A = Quantity B < Quantity C
