$\large \underline{ \underline{ \bold{ \: Explanation : \: \: \: }}}$

Let , Max's present age = x

A.T.Q ,

Cooper's present age = 3x --- eq (i)

After 3 Years

$\to$ Cooper's age = 10 + Max's age

$\to$ ( 3x + 10 ) = 10 + 2( x + 10 )

$\to$ 3x + 10 = 10 + 2x + 20

$\to$ 3x - 2x = 20

$\to$ x = 20

Put the value of x = 20 in eq (i)

$\to$ Cooper's present age = 3 × 20

$\to$ Cooper's present age = 60

Hence , the present age of cooper is 60
