Question
The ratio of the present ages of P and Q is 6:5
respectively. If the age of P 12 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.Solution
Let the present ages of P and Q be 6x and 5x years respectively. According to the question, => 6x + 12 = 2.25(5x – 4) => 6x + 12 = 11.25x - 9 => 5.25x = 21 => x = 4 Required age = 6x – 2 = 22 years
What value should come in the place of (?) in the following questions?
(√576 * 35 ÷7) * 20% of ? = 72
- What will come in place of the question mark (?) in the following questions?
18×4+96÷8=? Simplify: 3/4 of 2½ + 2/3 of 1½
276 ÷ 11.5 + 12 = ? x 3
√ 729 × 5 – 220 % of 15 + ? = 120% of 160
Simplify: (23×32) ÷6
What will come in the place of question mark (?) in the given expression?
{180 + (2250/15)} ÷ 11 = ?2 + 14
What will come in the place of question mark (?) in the given expression?Â
? X (62 - 20) + 60 X 5 = √1296 X 25 - 35 X 43...
What value should come in place of (?) question mark in the given expression.
75% of 320 + 40% of 150 = ?
2048 × 1824 ÷ 76 = (? - 212) × 64
