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.

Can anyone explain how (x+24)+2 is formed?
Faisal said:

It is Simple.
X is the age of son (added with the age of his father) and and 24 is the age of his father which increases by 2.

Anyone please answer me,
They have asked present age of son right?
Then it must be (22-2) = 20.

How come 2 (x+2) ?
Devi said:

I think it should be 20 years because present age is asked.

I don't know why the answer is 22?
It must be 20 years, because you have to find the present age not the age after 2 years.
So, 2 years must be subtracted from 22 to get the true answer.

@ALL.
Let
x be fathers age,
y be sons age,
so,
present age,
equ (i)... ..
x=y+24,
after 2 yrs,
equ (ii)... ..
x+2=2(y+2) -------{by rewriting x= 2y+2},
Because 2 will be added in their present age i.e in x & y, and not in equ (i)
Then (x+2 fathers age) will be = 2 * (the age of son y+2).
then put value of x from equ (ii) in equ (i) to get y(sons age).
i.e y=22.

Father is 24 yrs older than son
after 2 yrs father will be twice so we write father2 and son 1
so difern b/w 2 and 1 is of =1
so the value of 1 is 24.
24 * 2 =48,
24 * 1=24,
48-2 yrs = 46.
24-2=22 answer.

@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.
