Question

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

Answer 1

Here in this question the relation is between Ravi s Present Age and His Age after 15 years is given and we have to find Ravi s present age.

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.
