A man is 24 years older than his son. In two years, his age will be twice the age of his son. The present age of his son is:
Answer: Option
Explanation:
Let the son's present age be x years. Then, man's present age = (x + 24) years.
(x + 24) + 2 = 2(x + 2)
x + 26 = 2x + 4
x = 22.

Let's son age =x
Father age= -+24
The ration between father and son is always equal,
X=x+24.
After 2 years;
Father age also increases and don age also,
X+2= x+24+2.
But we have one condition,
After 2 years father age is twice than son age,
So.
2(x+2)= x+24+2.
Simplify;
2x-x =24+2-4,
X=22,
X is son age =22.
According to the question
When son age is 1-year father is 24 years.
1:24
Now, when son age is 22.
Father age= 22+24=46 years.
Father age= -+24
The ration between father and son is always equal,
X=x+24.
After 2 years;
Father age also increases and don age also,
X+2= x+24+2.
But we have one condition,
After 2 years father age is twice than son age,
So.
2(x+2)= x+24+2.
Simplify;
2x-x =24+2-4,
X=22,
X is son age =22.
According to the question
When son age is 1-year father is 24 years.
1:24
Now, when son age is 22.
Father age= 22+24=46 years.

Here we assumed as the sons's present age as x. And through the problem we are finding the value of 'x'.that means present age.so no need to subtract that 2 years from 22. The son's present age is 22.

Age difference will be 24.
And after 2 years father's age will be twice as son's age. So 14, 18, 20 will not be answer.

@Srikanth.
In another 2 years, son's age X will become X+2. So it is written as X+2.
Hence in question after two years father age will be twice of son's age so 2 (X+2).
In another 2 years, son's age X will become X+2. So it is written as X+2.
Hence in question after two years father age will be twice of son's age so 2 (X+2).

@Rachana Manek
You should take father and son's age.
so U take both the ages in both sides
SO,
(x+24)+2=2(X=2)
(x+24)+2 means
Farther's age +2 years,
2(x+2) Means
Son's Age then 2 is used for twice as father age.
Now clear,then solve the equation.. you ll get the ans..

@vaishali.
The question its self saying that "In two years, his age will be twice the age of his son. " so we are adding "+2" on both sides means on fathers age and sons age. Ok I hope you understand.
