Question
Vessel A contains a mixture of milk and water, with 30
liters of milk. Vessel B also contains a milk-water mixture in the ratio of 5:4. The combined quantity of mixtures in vessels A and B is 140 liters, and the amount of water in vessel B is twice that in vessel A. Determine the quantity of mixture in vessel A.Solution
Milk in vessel A = 30 liters A + B = 140 liters Water in vessel B = 4x Milk in vessel B = 5x Water in vessel A = 4x/2 = 2x 30 + 2x + 4x + 5x = 140 11x = 110 x = 10 Water in vessel A = 2 * 10 = 20 liters Total quantity in vessel A = 20 + 30 = 50 liters Hence answer is option A
