Let A’s age be x years. B’s age = 2x and C’s age = (4 + x) According to question, => x + 2x + (4 + x) = 64 => 4x = 60 => x = 15 B’s age = 2x = 30 years C’s age = 4 + x = 19 years Difference between the ages of B and C = 30 – 19 = 11 years
7/11 × 1034 + 1(4/7) × 2401 = 1230 +?
30, 39, 66, ? , 174, 255
44% of 1250 + 46 × 34 = 40% of ? + 1154
Solve.
15.73 +13.25 +16.73 – 28.71 = 5 ×?
4/5 + 6/7 × 14/42 ÷ 24/35 = ?
4(1/3) × 2(11/14) = 50% of ? + 86/11
(30 × 0.80)⁴ ÷ (2160 ÷ 60)⁴ × (54 × 16)⁴ = (6 × 4)?+5
290 × 15 ÷ 5 + 34 + 50 = ?
17.5% of 400 – 24% of 150 = ?
