In a mixture of 100 litres of milk and water, the ratio of milk and water is 3 : 2. If this ratio is to be 1 : 1, how much more water is to be added to the mixture?
Answer & explanation
Correct answer: option 4
M : W
3 : 2
⇒ Quantity of solution = 100 Liters
⇒ (3 + 2)x = 100
⇒ 5x = 100
⇒ x = 20 Liters,
Amount of water to be added to make ratio 1 : 1,
⇒ 3 X 20 : 2 x 20 = 60 L : 40 L
⇒ 60 = 40 + x
⇒ x = 20 Liters.
