Ratio of milk and water in these mixtures are 7 ? 13, 4 ? 1, 1 ? 3 and 11 ? 9

∴ Percentage of milk in these mixtures will be 35%, 80%, 25% and 55%

Quantity of water in the jar D is 22 LITRES less than the quantity of milk;

Since quantity of milk in jar D is 55% and water is 45%;

∴ 0.55x – 0.45x = 22

⇒ x = 220 litres

∴ Quantity of water in the jar D = 0.45 × 220 = 99 litres

The quantity of milk in jar B is 100 litres;

TOTAL quantity in jar B = 100/0.8 = 125 litres

∴ Quantity of water in jar B = 125 – 100 = 25 litres

If total quantity of water in jar B, C and D is 229 litres;

∴ Quantity of water in jar C = 229 – 99 – 25 = 105 litres

Total quantity in jar C = 105/0.75 = 140 litres

And quantity of milk in jar C = 140 – 105 = 35 litres

Let the total quantity in jar A = y litres

According to the question;

After mixing jar C with jar A, quantity of milk;

∴ 0.35y + 35 = (y + 140) × 0.28

⇒ 0.07y = 4.2

⇒ y = 60

∴ Total quantity in jar A = 60 litres

∴ Quantity of water in jar A = 60 × 0.65 = 39 litres
