Question

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:

current age of ravi = x

after 15 years,

Ravi's age = x+15

atq,

x+15= 4 times of x

x+15 = 4x

15= 4x-x

3x= 15

x= 5

current age of ravi = 5 years old.

Answer 2

Answer:--

Solution:-

Let present age is X years.

Then, Fifteen years later , his age will be 4x years.

Ravi s Age after 15 Years be : (X+15) Years

Now also his age after 15 years will be four times his present age.

Therefore,

⇒  4X = (X+15)  

⇒ 4X - X = 15

⇒ 3X = 15

⇒ X = (15/3)

⇒ X = 5.

Hence, Ravi s Present age is 5 Years.
