Question

difference between 3/5 of Raman's present age and his age 4 years ago is zero . what will be his age after 5 years?

​

Answer 1

Step-by-step explanation:

let the present age of Raman be x

3/5 of Raman present age = 3x/5

before 4 year

Raman age be x-4

a/q,

3x/5-(x-4)=0

3x/5 -x+4=0

4= x-3x/5

4= 2x/5

20= 2x

10= x

Raman age after 5year be (x+5)

= 14

#666

Answer 2

Answer:

After five years Raman's age would be $15$ years.

Step-by-step explanation:

Let Raman's present age be $x$.

So we need to get $3/5$ of his present age  and his age four years ago. Then we subtract it and equates with zero to get his present age, after that we can find his age after five years.

$3/5$ of Raman's present age $=\frac{3x}{5}$

Four years ago his age was $=x-4$

And the difference between them is zero.

That is,   $\frac{3x}{5} - (x-4)=0$

             $\frac{3x}{5} =x-4\\\\3x=5(x-4)$

                  $=5x-20$

      Implies   $5x-3x=20$

                      $2x=20$

Therefore  $x=10$.

That is Raman's present age is ten years.

Hence after five years his age would be $15$ years.

Hence the answer
