Let P’ age at the time of his marriage 8 years ago be 3x. His present age be = (5/3) × 3x = 5x According to question, => 5x – 3x = 8 => x = 4 years Now P’ age at the time of his marriage 8 years ago = 3x = 3 × 4 = 12 years And his present age = 5x = 5 × 4 = 20 years P’s sister age 8 years ago = 12 – 10 = 2 years So, present age of P’s sister = 2 + 8 = 10 years
(2 ÷ 3) × (4 ÷ 12) × (? ÷ 10) × 45 × (1 ÷ 5) = (? ÷ 6) + (2 ÷ 5)
(3984 ÷ 24) x (5862 ÷ 40) = ?
641.5 + 72 × 8 = ? × 4
What will come in place of (?) in the given expression.
{(60% of 250) + √144} ÷ (3² - 4) = ?
72% of 486 – 64% of 261 = ?
[√441 ÷7] × 40% of ? = 500 – 12.5% of 400
240 × 2.5 + 65 × 2/13 = ?2 - √225
