Question

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

Answer 1

Step-by-step explanation:

Let Ravi s present age be X 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. (When Times is given means we have to product it). Therefore,

4X = (X+15)

=> 4X - X = 15

=> 3X = 15

=> X = (15/3)

=> X = 5.

Hence Ravi s Present age is 5 Years.

Answer 2

let Ravi's present age be 'x' yr

given, 15yr hence his age is four times his present age..i.e,

(x+15)=4(x)

(4x-x)=15

3x=15

x=5yr
