Hey friend your answer is here
$let \: riddhima \: age \: be \: x \\ riddhima \: uncle = 4x \\ then \: after \: 8 \: year \\ riddhima \: age = x + 8 \\ riddhima \: uncle = 4x + 8 \\ according \: to \: question \\ riddima \: uncle \: age = 3 \times riddhima \: age \\ 4x + 8 = 3(x + 8) \\ 4x + 8 = 3x + 24 \\ 4x + 8 - 3x - 24 = 0 \\ x - 16 = 0 \\ x = 16 \\ riddhima \: age \:i s \: 16years \\ and \: riddhima \: uncle \: age = 4(16) \\ = 64years$
