Answer» Let ‘a’ be the number of litres of milk to be added. Given the ratio of milk and WATER before and after MIXING with milk as 3 : 2 and 4 : 1 respectively. Equating the quantity of milk present in the INGREDIENTS to the FINAL mixture we have, 0.6 × 40 + a = 0.8 × (40 + a) ⇒ 0.2 × a = 0.2 × 40 ⇒ a = 40 ∴ Quantity of milk to be added is 40 litres. |
