Question
99 ml of mixture ‘P’ contains milk and water
in the ratio of 7:4, respectively is mixed with 30 ml of mixture ‘Q’ containing milk and water in the ratio of 3:2, respectively. Find the ratio of milk to water in the resulting mixture.Solution
Quantity of milk in mixture P = 7/11 × 99 = 63 ml Quantity of water in mixture P = 4/11 × 99 = 36 ml Quantity of milk in mixture Q = 3/5 × 30 = 18 ml Quantity of water in mixture Q = 2/5 × 30 = 12 ml Desired Ratio = (63 + 18):(36 + 12) = 81:48 = 27:16
15.99% of 549.99 ÷ 11.17 = ? ÷ 20.15
74.91% of 639.95 – 599.98% of 45 + 119.987 = ?
(4.88 × 5.76)2 - ?2 = 39.89 × 19.86

(1800.23 ÷ 29.98) + (816.32 ÷ 23.9) + 1634.11 = ?
1449.98 ÷ 50.48 × 10.12 = ? × 2.16
36.05 × 5.02 + 12.052 = ? + 9.09 × 4.04Â
(31.9)3 + (34.021)² - (16.11)3 - (42.98)² = ?
