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.

Guys.
Because both father and son ages are increasing. If father age increases two years so sons are will be increased.

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.

@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.

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.

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

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.

Isn't it 20 years?
He is 22 years only after 2 years. To find the present don't we have to subtract 2years from 22?
Please tell me.
