In 60 litres mixture of milk and water, the ratio of volumes of milk and water is 3 : 2. If we want the ratio of the volumes of milk and water to be 1 : 1, then how much water should be added to the mixture?
Answer & explanation
Correct answer: option 3
M : W = 3 : 2,
Quantity of mixture = 60 L
⇒ (3 + 2)x = 60,
⇒ 5x = 60,
⇒ x = 12 L
⇒ Milk = 3 x 12 = 36 L, Water = 2 x 12 = 24 L
⇒ Amount of water to be added to make ratio 1 : 1,
⇒ Milk = Water
⇒ 36 = 24 + x
⇒ x = 36 - 24
⇒ x = 12 Liters,
Hence, 12 Liters water should be added to make the ration of milk and water 1 : 1.
