Question
The ratio of the present ages of P and Q is 7:4
respectively. If the age of P 13 years hence from now will be 125% more than the age of Q 4 years ago from now, then find the age of P 2 years ago from now. TYPE 8Solution
Let the present ages of P and Q be 7x and 4x years respectively. According to the question, => 7x + 13 = 2.25(4x – 4) => 7x + 13 = 9x - 9 => 2x = 22 => x = 11 Required age = 7x – 2 = 75 years
What will come in the place of question mark (?) in the given expression?
√1936 + (84 ÷ 2 × 1.5) – 35² + 18² = ?
13.5% of (100 + ?) = 27
The value of ((0.27)2-(0.13)2) / (0.27 + 0.13) is:
- Evaluate: 168 ÷ 12 × 5 + 190 – 20% of 450
The value of 42 ÷ 9 of 6 - [64 ÷  48 x 3 – 15 ÷ 8 x (11 – 17) ÷ 9] ÷ 14 is:
60% of 250 + 14 × 10 - 210 = ?
- What will come in place of (?) in the given expression.
(84 + 36 ÷ 6) × 2 = ? What will come in the place of question mark (?) in the given expression?
(17/27) of 162 + ?² = 632 - (73 - 12) X 5- What will come in the place of question mark (?) in the given expression?
[{(224 + 14 × 23) – 187} × (672 ÷ 28 – ?)] = 1795 118 × 6 + 13 + 83 = ?
