Let their present age be 5x and 3x respectively. Product of their ages = 15x² = 1500 => x² = 100 => x = 10 Present age of A = 5x = 50 years Present age of B = 3x = 30 years Ratio of their ages after 2 years = (50+2) : (30+2) = 52:32 = 13:8
√2703.88 × √784.15 – 26² = ? - (34.85)²
119.98% of 80.02 - 15.12 × 2.02 + 19.95 = ?

18.99% of (102.99 + 98.01) + 6.01³ - (9.02 of 2.99) = ? of (64.02 - 28.98)
12, 16, ?, 36, 52, 72
? = 540.24 + 1022.97 – 11.992
999.99 + 99.99 + 99= ?
(9116.89 – 8024.89 + 902.95) × 14 = 1800 × ?
