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.

Let Arun = A
Let Deepak = D
A/D = 3/4
4A - 3D = 0 ---------> (i)
After 6 years, Deepak.
D + 6 = 26.
thus D = 20.
Put this value of D in equation i.
thus , 4A = 60
Thus A = 15 years.
Let Deepak = D
A/D = 3/4
4A - 3D = 0 ---------> (i)
After 6 years, Deepak.
D + 6 = 26.
thus D = 20.
Put this value of D in equation i.
thus , 4A = 60
Thus A = 15 years.

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.

Let Arun's age be =x.
Let Deepak's age be =y.
Given:
x/y = 4/3 ------->equation 1
After 6 years:
x + 6 = 26 ------> equation 2
Solving equations 1 and 2 we get,
20/y = 4/3.
4y = 60.
y = 15.
Let Deepak's age be =y.

20/y = 4/3.
4y = 60.
y = 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).

Let x is age of arun and y is age of deepak
Since, X/Y =4/3
then 3X =4Y
Finally X = 4/3Y ---> Eqn 1
After 6 years age of arun will be 26,
X + 6 = 26 ----> Eqn 2
Substitute Eqn 1 into Eqn 2.
4/3Y + 6 = 26
4Y + 18/3 =26
4Y + 18 = 78,
4Y = 60.
Therefore Y = 15.

Gud morning.
Arun: Deepak=4:3 [at present]
So,let=4x:3x.
Gn that after 6 years arun age is 26,
So,
4x = 26.
4X = 20.
X = 5.
Deepak age = 3x.
=3 * 5
=15.

By given information 4:3 = 4=20.
hence 20/4=5.
therefore 5*3=15(ans).
hence 20/4=5.
therefore 5*3=15(ans).

Consider son's age as 'x' and father's as 'y' so,
x + y = 60.
Then six years ago,
y-6 = 5(x-6).
y-6 = 5x-30.
y = 5x-24.
x+5x-24 = 60.
6x = 84.
x = 84/6 = 14.
So after 6 years 14 + 6 = 20 years old.
x + y = 60.
Then six years ago,
y-6 = 5(x-6).
y-6 = 5x-30.
y = 5x-24.
x+5x-24 = 60.
6x = 84.
x = 84/6 = 14.
So after 6 years 14 + 6 = 20 years old.

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.

There given that the present age of arun and Deepak are 4:3.
So first of all consider the aruns age as 4x and Deepak age is 3x.
And next there is given after 6 means then aruns age after 6 years means 4x+6.
And there is alredy given aruns age is 26 compare both ages i.e. 4x+6=26->4x=20->x=5.
Here we get x=5 then consider present age of Deepak age is 3x so substitute x value there the we get his age is 15 so answer is 15.
