The present age of A is 8/3 times to that of his marriage age. Present age of his brother is 1/4th of his present age. If A was married 40 years ago then find the present age of his brother.
Let the age of A when he was married be x years. Present age of A = 8x/3 Present age of his brother = (1/4)×(8x/3) = 2x/3 According to Question, => x + 40 = 8/3x => 5/3x = 40 => x = 24 years Present age of his brother = (2/3) ×24 = 16 years
