A mixture contains milk and water in the ratio 4 : 3 (by volume). If 4 litres water is added to it, then the ratio becomes 1: 1. What is the quantity of milk in the initial mixture?
Answer & explanation
Correct answer: option 1
Initial Solution,
Milk : Water
4 : 3,
After adding 4 liters of water,
Milk : Water
1 : 1,
⇒ Making Milk in both solutions equal, we multiply final solution with 4,
⇒ (1 : 1) x 4 = 4 : 4,
⇒ Final solution water ratio - Initial solution water ratio = 4 liters,
⇒ (4 - 3)x = 4 L
⇒ x = 4 L,
Hence, The quantity of milk in the initial mixture = 4 x 4 = 16 liters.
