Question

Rohan is three times older than Dinesh. Five years ago, he was four times older than Dinesh.
How old is Rohan?​

Answer 1

Answer:

Given,

Rohan is 3 times older than Dinesh.

So let us consider Dinesh's age be ' x'  and Rohan's age be 3x

5 years ago,

Rohan's age =  3x -5

Dinesh's age = x -5

Also given that 5 years ago, Rohan was 4 times older than Dinesh

 ∴ $3x - 5 = 4(x - 5)$

   $3x - 5 = 4x - 20$

  $4x - 3x = 20 - 5$

  $x = 15$

Therefore age of Rohan = 3x

                                        = 3 × 15

                                        = 45
