Question
150 litres of a mixture contains 30% milk and rest
water. If ‘x’ 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 ‘x’.Solution
Quantity of milk in the initial mixture = 150 × 0.30 = 45 litres Quantity of water in the initial mixture = 150 – 45 = 105 litres Quantity of water is unchanged in the final mixture. So, Quantity of final mixture = (105/30) × 100 = 350 litres Quantity of milk in final mixture = 350 – 105 = 245 litres Value of ‘x’ = 245 – 45 = 200

? = 38.97² ÷ (3.99⁵ + 5.89 × 107.32) + 58.24% of (512.12 × 21.07)
(363.89% of 224.98 – 319.86% of 134.94) ÷ ? = √(134.88 ÷ 15.25)
111.89 × 4.12 – 504.04 ÷ 2.12 = 170.12 + ?
(29.892 × √290) + 32.98 × 6.91 = ?
