Question

Arjun is twice as old as shriya.Five years ago his age was three times shriya's age.Find their parents age.

Answer 1

Answer:

Shriya's age=x

=5years

Arjun's age=2x

=10years

Step-by-step explanation:

Let Shriya's age be x

and Arjun's age be 2x

According to the question :-

2x+5=3x

5=3x-2x

5=x

Shriya's age=x

Shriya's age=x =5years

Shriya's age=x =5yearsArjun's age=2x

Shriya's age=x =5yearsArjun's age=2x =10years

Answer 2

solution:

$\footnotesize\texttt{Let us take shriya's age be x years. }$

$\footnotesize\texttt{then arjun's present age would be 2x years.}$

$\footnotesize\texttt{shriya's age five years ago was (x-5) years. }$

$\footnotesize\texttt{arjun's age five years ago was (2x-5) years. }$

$\footnotesize\texttt{it is given that arjun's age five.}$

$\footnotesize\textsf{ year ago was three times shriya's age.}$

Thus,

➠$\small\mathtt{2x-5=3(x-5) }$

➠$\small\mathtt{2x-5=3x-15 }$

➠$\small\mathtt{15-5=3x-2x }$

➠$\small\mathtt{10= x }$

➠so,shriya's present age =x =10 Years .

➠therefore, arjun's present age =2x=2×10=20 years.
