A mixture contains milk and water in the ratio 5 : 2 If 4 litres of water is added to the mixture, the ratio becomes 5 : 4. What is the quantity of milk in the given mixture?
Answer & explanation
Correct answer: option 4
Milk : Water
5 : 2
After adding 4 litres of water, ratio becomes
5 : 4
Thus, 2R = 4 (difference in ratio of water, because ration of milk is equal)
R = 2
Quantity of milk = 5 x 2 = 10 litres
