Question
In a 180-liter mixture, there is a ratio of 11:7 between
Milk and Glucose. How much additional Glucose should be added to the mixture so that the quantity of glucose becomes 50% of the resultant mixture?Solution
ATQ, Quantity of Glucose in the initial mixture = 180 × (7/18) = 70 liters Quantity of Milk in the initial mixture = 180 × (11/18) = 110 liters Since, we’re not adding Milk, 110 litres of Milk will represent 50% of the new mixture. So, total quantity of resultant mixture = 110 ÷ 0.5 = 220 liters Quantity of Glucose to be added = 220 – 180 = 40 liters
