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

Answer 1

Answer: 5 years .

Step-by-step explanation:

Let Ravi's present age be x years .

Ravi's age 15 years from now will be (x + 15) years .

Also it is given that ravi's age will be 4 times his present age , which is 4x years .

∴ 4x = x + 15

⇒ 3x = 15

⇒ x = 5

So Ravi's present age = x = 5 years .
