Question
The present ages of 'Aman' and 'Ravi' are in the ratio
5:6. Two years from now, Aman’s age will be 25% less than Ravi’s age. Find Aman’s current age.Solution
Let present ages of Aman and Ravi be 5x and 6x years respectively. According to the question, (6x + 2) × 0.75 = 5x + 2 Or, 4.5x + 1.5 = 5x + 2 Or, 0.5x = 0.5 So, x = 1 Present age of Aman = 5 × 1 = 5 years
14.99% of 7820 + 5535.25 ÷ 123.001 - ? = 84
(15.15 × 31.98) + 30.15% of 719.99 = ? + 124.34
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
7/12 of 539.98 – 23.98 × 9.03 + 77.89 = ?
24.11 × 5.98 + 25.03 × 3.12 – 34.99 + 96.9 × 5.02 =?
(29.98% of 9840) + ? + (19.899% of 8490) = 7560
13³ + 1.3² + 1.03¹ + 1.003 = ?
