Answer 2

Concept Introduction:-

It may be in the form of a word, a symbol, or a figure that reflects the arithmetic value of a quantity.

Given Information:-

We have been given that Ravi is twice as old as suresh, three years ago he was three times as old as suresh.

To Find:-

We have to find that age of Ravi.

Solution:-

According to the problem

Consider the present ages of Ravi and Suresh are $x$ and $y$ respectively ,then

from statement $1$ we have Ravi age is twice of Suresh

so $x=2y$ → equation $1$

from statement $2$ we have three years ago which means when Suresh is $y-3$ and Ravi is $x-3$, Ravi age is thrice of Suresh

so $(x-3)=3(y-3)$ by solving it

we have $x=3y-6$ → equation $2$

substitute $x=2y$ from equation $1$ in equation $2$

hence

$2y=3y-6\\y=6$

From our assumption $y$ is suresh age

So suresh age is $6$

Then present Ravi Age becomes double that of suresh present age

$2\times$age of suresh $= 2\times 6=12$

Final Answer:-

The Present age of Ravi is $12$.
