Answer 2

Solution :

$\bf{\red{\underline{\tt{Given\::}}}}$

Arjun is twice as old as Shriya. Five years ago his age was three times Shriya's age.

$\bf{\red{\underline{\tt{To\:find\::}}}}$

Their present ages.

$\bf{\red{\underline{\tt{Explanation\::}}}}$

Let the present age of Shriya be r years.

Let the present age of Arjun be 2r years.

A/q

$\underbrace{\bf{5\:years\:AgO\::}}}}}$

The age of Shriya be (r-5) years.

The age of Arjun be (2r-5) years.

So;

$\longrightarrow\sf{3(r-5)=(2r-5)}\\\\\longrightarrow\sf{3r-15=2r-5}\\\\\longrightarrow\sf{3r-2r=-5+15}\\\\\longrightarrow\sf{\pink{r=10\:years}}$

Thus;

$\underline{\sf{The\:present\:age\:of\:Shriya\:=r=10\:years}}}}\\\underline{\sf{The\:present\:age\:of\:Arjun\:=2r=2*10=20\:years.}}}}$
