Answer:
This is the answer.Soms age is 15 and Father's age is 45
[tex] \underline { \pink { At \: present : }}[/tex]
Age of Arun = x years ,
Age of Arun's father = 3x years
[tex] \underline { \pink { After \:15\: years: }}[/tex]
Age of Arun = ( x + 15 ) years ,
,Age of Arun's father = ( 3x + 15 ) years
/* According to the problem given */
[tex] ( 3x + 15 ) = 2( x + 15 ) [/tex]
[tex] \implies 3x + 15 = 2x + 30 [/tex]
[tex] \implies 3x - 2x = 30 - 15 [/tex]
[tex] \implies x = 15 [/tex]
Therefore.,
[tex] \red { Present \: age \: of \: Arun } \green { =15 \: years } [/tex]
[tex] \red { Present \: age \: of \: Arun's \: Father } \green {= 45\: years } [/tex]
