Answer» Correct Answer - Option 1 : Quantity A > Quantity B Quantity A: Given that, mixture of 90 litres of the spirit and water contains 20% water. In the first mixture Water = (20/100) × 90 = 18 litres ∴ Spirit = 90 – 18 = 72 litres After adding some water to the mixture, water became 50% of the new mixture ∴ 72 litres of water in new mixture = 50% of new mixture ∴ Total litres of new mixture = (100/50 × 72) = 144litres So, water to be added = 144 – 90 = 54 litres Quantity B: 45 litres ∴ Quantity A > Quantity B |
