The ratio of age of A and his son is 9:5. If the difference of their ages 6 year ago is 12, then find the sum of ages of A and his son 15 year hence?
Let the present age of Raman and his son be 9x and 5x respectively. => 9x – 5x = 12 ∴ x = 3 Required sum = 14 × 3 + 30 = 72 years
√323.89 × (3.20) ÷ 9.02 =?
599.9 - ? + 64.9 = (5% of 300.012) × 10.032
20.05% of 150.05 – 12.15% of 99.99 × 2.02 = ?
35.05% of 14.87 × (13.02 – ?) + 30.19 = 188.7
14.232 + 19.98% of 629.99 = ? × 6.99
95.001% of 8219.99 - 4/9 % of 5399.98 + 109.99 = ?
(33.95)2 – (25.004)2 + (18.0099)2 – (9.07)2 = ? - (14.990)2
25.22% of (59.9 × 8.01) + 69.97 =?
13³ + 1.3² + 1.03¹ + 1.003 = ?
