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.

After 6 years means 15 +6= 21 years?

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.

NEW METHOD:
Arun and Deepak age is in the ratio 4:3.
After 6 years Aruns age is 26. So current age of Arun is 26-6 = 20.
4:3 = 20:Deepak.
4*Deepak = 20*3.
Deepak = 60/4 = 15.

Let arun age is x and deepak age is y.
According to question,
x/y= 4/3 -- (1)
x+6=26
x=20.
From(1)
y=(3/4)*x
Put x=20
y=(3/4)*20
y=15
So deepak age is 15 years.

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.

Arun age 4x+6=26----------->1
4 is ratio x is variable n 26 is his present age
Deepak age y=3x------------>2
Here y is taken for just to equate, x is variable
Now simplify eq 1
4x=26-6 ==> x=5
Sub x value in eq 2
y=3*5 (y is deepak's age)
y=15
That's it:)

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
