Question
3 liters of a liquid having milk and water in the ratio
3: 2 is mixed with 3 liters of a liquid having milk and water in the ratio 2: 3. Find the ratio of milk to water in the new mixture.Solution
Let the common ratios be x and y in respective cases. In the mixture of 2 liters, Quantity of milk = 2 × 3x/5x = 1.2 liters Quantity of water = (2 - 1.2) = 0.8 liters In the mixture of 3 liters, Quantity of milk = 3 × 2y/5y = 1.2 liters Quantity of water = (3 - 1.2) = 1.8 liters Hence in the new mixture, Quantity of milk = 1.2 + 1.2 = 2.4 liters Quantity of water = 0.8 + 1.8 = 2.6 liters The ratio of milk to water in the new mixture = 2.4: 2.6 = 12: 13 ∴ The ratio of milk to water in the new mixture is 12: 13.
(500 × 6 ÷ 10) - (√256 + 8) = ?
22% of 400 + √ ? = 34% of 800 - 25% of 400
(2/5)(32% of 4500 – 440) = ? × 8
1550 ÷ 62 + 54.6 x 36 = (? x 10) + (28.5 x 40)
What will come in the place of question mark (?) in the given expression?
96 ÷ (9 - 6.6) + 17.5 X 6 = ? ÷ 8
13 X ? = 85 X 4 + √81 + 2
45% of 360 - 160 + ? = √324
((67)32 × (67)-18 / ? = (67)⁸
4567.89 - 567.89 - 678.89 = ?
82.3 × 644.7 × 723.4 × 815.85 = 72?
