A drink of chocolate and milk contains 8% pure chocolate by volume. If 10 liters of pure milk are added to 50 litres of this drink, the percentage of chocolate in the new drink is:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 6.
In 50 litres of the chocolate solution,
Chocolate = 8% of 50 = 4L.
Milk = 50 - 4 = 46L.
Now 10 litres of pure milk is added.
Now the concentration of milk = 46 + 10 = 56L
Total concentration of solution = 56 + 4 = 60L
% of chocolate = 4/60 × 100 = 6%.
