Step-by-step explanation:

Let the present ages of Arun and Deepak be 4x years and 3x years respectively. Then,

4x + 6 = 26

⇒ 4x = 20

⇒ x = 5

∴ Deepak's age = 3x = 15 years.

Answer 2

let Arun age and Deepak age be 4x and 3x

Arun's age after six years = 4x + 6

But Arun's age after six years is also 26

=> 4x + 6 = 26

=> 4x = 26-6

=> 4x= 20

=> x = 20/4

=> x = 5

Deepak's age is 3x => 3 × 5 = 15 years

B) 15 years is correct...
