Answer 1

QUESTION::

15 years from now Ravi's age will 4 times his present age. what is Ravi's present age?

_________________________

ANSWER::

Let Ravi's age be x.

According to question;

After 15 years his age will be 4 times his present age.


Equation according to question;

=> x + 15 = 4x

=> 4x = x + 15

=> 4x-x= 15

=> 3x = 15

=> x = $\frac{\large{15}}{\large{3}}$

=> x= 5

OR

=> x + 15 = 4x

=> 4x = x + 15

=> 4x-x= 15 + x-x

=> 3x = 15

=> $\frac{\large{3x}}{\large{3}}$ = $\frac{\large{15}}{\large{3}}$

=> x= 5

THUS, RAVI'S AGE IS 5 YEARS.
