Answer» A has 36% spirit. Amount of spirit in 2 liters of A = 0.36 × 2 = 0.72 liters B has 40% spirit. Amount of spirit in 4 liters of B = 0.4 × 4 = 1.6 liters Total amount of mixture = 2 + 4 = 6 liters Amount of spirit in the FINAL mixture = 0.72 + 1.6 = 2.32 liters Amount of water in the final mixture = 6 – 2.32 = 3.68 Required RATIO = 2.32 : 3.68 = 29 : 46 |
