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: Option
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.

Why not it is 11?
Because we calculated the x value using Arun's age after 6 years so when we got an answer as 15 we have to deduct that 6 years right.

ARUN = 4X.
DEEPAK = 3X.
WE HAVE TO FIND DEEPAK'S AGE,
ie.3X = ?.
4X+6 = 26.
4X = 20-6.
4X = 20.
X = 20/5.
X = 5.
SO, 3X = 3*5 = 15.
DEEPAK = 3X.
WE HAVE TO FIND DEEPAK'S AGE,
ie.3X = ?.
4X+6 = 26.
4X = 20-6.
4X = 20.
X = 20/5.
X = 5.
SO, 3X = 3*5 = 15.

Let Arun's present age be 4x and Deepak's age be 3x.
4x + 6 = 26,
4x = 20,
x = 5.
Deepak present age = 3x = 3(5) = 15 years.
4x + 6 = 26,
4x = 20,
x = 5.
Deepak present age = 3x = 3(5) = 15 years.

After 6 years the age of Arun = 26.
Present age of Arun is 26-6 = 20.
=> 4/3 = 20/x.
=> x = 20*3/4.
=> x = 15.
Present age of Arun is 26-6 = 20.
=> 4/3 = 20/x.
=> x = 20*3/4.
=> x = 15.

Deepak = 4x + 6 = 26.
= 26 - 6 = 20.
4x = 20.
x = 5.
Arun = 3x.
= 3 x 5.
= 15 (ANS).
= 26 - 6 = 20.
4x = 20.
x = 5.
Arun = 3x.
= 3 x 5.
= 15 (ANS).

Age =x
Ration of arun and deepak is 4:3
After 6 year arun age wil be 26
So, 4x+6=26
= x=5
Deepak age wil be =3x=15
Ration of arun and deepak is 4:3
After 6 year arun age wil be 26
So, 4x+6=26
= x=5
Deepak age wil be =3x=15

Given that Arun and Deepak age are in the ratio 4x:3x.
Arun age after 6 years is 4x+6=26.
X=5.
3x=15.
Arun age after 6 years is 4x+6=26.
X=5.
3x=15.

The answer derived is not very clear. Most descriptions required before the last step.
