Answer 2

$Let \:Present \: age \:of \: Akbar = x \:years$

$Present \: age \:of \: Amar = 2 \times Akbar \:age \\= 2x \: years$

$\underline { \blue { After \: 5 \: years : }}$

$Age \: of\: Akbar \: will \:be = (x + 5 )\:years$

$Age \: of\: Amar \: will \:be = (2x + 5 )\:years$

/* According to the problem given */

$\frac{(2x+5)}{x+5} = \frac{5}{3}$

$\implies 3(2x+5) = 5 (x+5)$

$\implies 6x + 15 = 5x + 25$

$\implies 6x - 5x = 25 - 15$

$\implies x = 10$

$Now, \red{ \:Present \: age \:of \: Akbar}\green { = 10 \: years}$

$\red{ \:Present \: age \:of \: Amar} =2 \times 10 \: years\\\green { = 20 \: years }$
