Question

Arjun is twice as old as shriya five years ago his age was three times riyaz age find their present ages

Answer 1

Step-by-step explanation:

let us consider Arjun age as x years and shriya age y years.

y = 2x------------(1)

y-5 = 3(x-5)-----------(2)

Substitute equation (1) in equation (2).

y-5 = 3(x-5)

2x-5 = 3x-15

15-5 = 3x-2x

10 = x

Substitute x = 10 in equation (1)

y = 2x

y = 2(10)

y = 20

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.
