100 liters of a mixture contains milk and water in the ratio 4 : 1 . if 10 liters of this mixture be replaced by 10 liters of milk , the ratio of milk to water in the new mixture would be ?
"quantity of milk in 100 liters if mix = 100 * 4 / 5 = 80 liters quantity of milk in 110 liters of new mix = 80 + 10 = 90 liters quantity of water in it = 110 - 90 = 20 liters ratio of milk and water in new mix = 90 : 20 = 9 : 2 answer is b"
divide(multiply(subtract(10, const_1), 1), multiply(4, 1))
