30 liters of a mixture contains milk and water in the ratio 2 : 1 . if 5 liters of this mixture be replaced by 5 liters of milk , the ratio of milk to water in the new mixture would be ?
"quantity of milk in 30 liters if mix = 30 * 2 / 3 = 20 liters quantity of milk in 35 liters of new mix = 20 + 5 = 25 liters quantity of water in it = 35 - 25 = 10 liters ratio of milk and water in new mix = 25 : 10 = 5 : 2 answer is d"
divide(multiply(subtract(5, const_1), 1), multiply(2, 1))
