Average age of A, B and C is 20 years. Average age of B and C was 12 years when A was born. If B is 21 years old, then, find the age of C, 6 years hence.
A + B + C = 60---------(i) (B + C) - A = 24 --------(ii) (since A was born) B = 21 years Now, substituting the value of B + C in equation I, we get => A + 24 + A = 60 => 2A = 36 => A = 18 so, B + C = 24 + 18 = 42 B = 21 years C = 21 years Age of C, 6 years hence = 21 + 6 = 27 years
(√4623.9 + √484.2) – √2303.97 ÷ √1296.4 × √35.98 ÷ √15.99 = ?
