Question
150 litres of a mixture contains 30% milk and rest
water. If βxβ litres of milk is added into the mixture then quantity of water in the final mixture becomes 30% of total quantity of mixture. Find the value of βxβ.Solution
Quantity of milk in the initial mixture = 150 Γ 0.30 = 45 litres Quantity of water in the initial mixture = 150 β 45 = 105 litres Quantity of water is unchanged in the final mixture. So, Quantity of final mixture = (105/30) Γ 100 = 350 litres Quantity of milk in final mixture = 350 β 105 = 245 litres Value of βxβ = 245 β 45 = 200
