Question
In a chemistry lab two beakers A and B contains 36% and
40% of spirit respectively. If two liters from A is mixed with 4 liters of B. The ratio of spirit and water in the resulting mixture is:Solution
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
