Question

At present, the ratio between the ages of Arun and Deepak is 4 : 3. After 6 years, Arun's age will be 26 years. What is the age of Deepak at present ?

Answer 1

hi 

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.

hope this will help you

Answer 2

let age of Arun be 4x and that of Deepak be 3x 
after 6 years, 
4x+6=26
4x=20
x=5
therefore age of Deepak = 3x
=3*5
15 years
