Question

Fifteen years from now Ravi age will be 4 times his present age. What is Ravi 's present age?

Answer 1

Answer:

present age=5 yrs

Step-by-step explanation:

Ravi,s age now= x yrs

fifteen yrs from now=(x +15)yrs

    ( x+15)=4 x present age=4x

     (x+15)=4x

x-4x=-15

-3x=-15

x=5 yrs

Answer 2

Let the present age of Ravi be x.

Fifteen years later, Ravi age will be x+15 years.

According to the question,

x + 15 = 4x

⇒ 4x – x = 15

⇒ 3x = 15

⇒ x = 15/3

⇒ x = 5

Therefore, Present age of Ravi = 5 years.
