Hi

Good question... Keep progressing...

Here is your answer---

Let the present ages of the Arjun and Deepak is 4x and 3x respectively.


After 6 years,

Age of Deepak = 3x +6

Age of Arjun = 4x +6


Given---
         Age of Arjun six years after is 26 years.

Therefore, 
                    4x + 6 = 26
                         4x =  26 - 6
                          4x =  20
                           x = 5 years

Thus,

For Arjun,

Present ages of Arjun =4x
 Present age of Arjun  = 4 * 5                       [Putting the value of x]
  Present age of Arjun = 20 years.

For Deepak,

Present age of Deepak = 3x
 Present age of Deepak= 3 * 5                     [Putting the value of x]
Present age of Deepak = 15 years

Answer 2

Answer:

Step-by-step explanation:

Let Arhun:Deepak = 4:3 = k

So, After 6 years Arjun's age is 26 years

That's why we can do =,

4k + 6 = 26

=> 4k = 26 - 6

=> 4k = 20

=> k = 5

Now, Deepak,s age = 3K

                                  = 3 * 5

                                  = 15 years
