$\huge \color {aqua} \boxed{ \colorbox{black} { \sf{to \: find}}}$

☆The age of Manu

$\huge \color {aqua} \boxed{ \colorbox{black} { \sf{given}}}$

☆Sonu's age is 2/3 rd of Manu's

☆After 5 years Sonu will be 45 years old

$\huge \color {aqua} \boxed{ \colorbox{black} { \sf{assuming}}}$

☆ Let the age of Manu be x

☆Therefore, sonu's age = 2/3 of x= 2x/3

$\huge \color {aqua} \boxed{ \colorbox{black} { \sf{solution}}}$

ATQ

$\frac{2x}{3} + 5 = 45 \\ = > \frac{2x + 15}{3} = 45 \\ = > 2x + 15 = 45 \times 3 \\ = > 2x + 15 = 135 \\ = > 2x = 135 - 15 \: \: \: \\ = > 2x = 120 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ = > x = \frac{120}{2} = 60$

$\huge \color {aqua} \boxed{ \colorbox{black} { \sf{hence}}}$

☆The age of Manu is 60
