Let the present age of B be x years. A’s present age = (x + 3) years C’s present age = (x - 4) years According to question, => [(x + 3) + 6]/(x -4) = 3/2 => x = 30 C’s age, 10 years ago = (30 - 4) – 10 = 16 years
13³ + 1.3² + 1.03¹ + 1.003 = ?
?% of (742÷ 7.911) = (11.01)2
(363.89% of 224.98 – 319.86% of 134.94) ÷ ? = √(134.88 ÷ 15.25)
6.992 + (2.01 × 2.98) + ? = 175.03
√323.89 × (3.20) ÷ 9.02 =?
? = 22.08 + 13.99 × 22.07
22.22 × 8.99 + 142.15 = ?
(17.98% of 249.99) - 4.998 = √?
