Question

Fifteen years from now Ravi age will be four times his present age .What is Ravi present age

Answer 1

Answer:

Ravi's present age : 5 years

Step-by-step explanation:

Let Ravi's present age be x,

Thus, 15 years from now = x + 15

According to question: x + 15 = 4x

>> x - 4x + 15 = 0

>> -3x = -15

>> x = -15 / -3

>> x = 5

Thus, Ravi's present age : 5 years

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.
