Let the present age of A, B and C be 4x, 5x and 7x respectively. According to the question, => A + B + C = 80 => 4x + 5x + 7x = 80 => x = 5 B’s age 15 years ago = 5x – 15 = 25 – 15 = 10 C’s age after 10 years = 7x + 10 = 35 + 10 = 45 Required ratio = 10 : 45 = 2:9
{(440.89 ÷ 20.74) ÷ 2.88} × 48.65 = ? 3
657.94 + 335.21 - 211.09 - 82.30 = ?
? = 41.92% of 49.96% of (45.07 1.97 – 4.98 2.03 )
49.96% of 120.21 + √(15) ÷ 1.87 × 4.41 = ?
35.05% of 14.87 × (13.02 – ?) + 30.19 = 188.7
32.052- 22.03 x 24.199 - 15.18 x 11.04 = ?
Solve the following expression and calculate the approximate value.
118.95 – 24.10 + (91.90 ÷ 22.89 × 12.14) = ?
1254.04 – 440.18 + 399.98 ÷ 10.06 = ?
49.99% of 539.99 + 263.98% of 49.99 = ?% of 1608.01
