                                13.
A person's present age is two-fifth of the age of his mother. After 8 years, he will be one-half of the age of his mother. How old is the mother at present?
 
                                    Answer: Option
                                                    Explanation:
                                                Let the mother's present age be x years.
| Then, the person's present age = | ![]()  | 
    2 | x | ![]()  | 
    years. | 
| 5 | 
![]()  | 
    ![]()  | 
    2 | x + 8 | ![]()  | 
    = | 1 | (x + 8) | 
| 5 | 2 | 
 2(2x + 40) = 5(x + 8)
 x = 40.

                After 8 years, the age of the mother is 40 years.

                What is the age difference between mother and person?

                32 will be the answer. In all the solutions 8 is added to find the age. So definitely 40 is not the answer.

                40 is the age of mother after 8 years. So we must subtract 8 from it.

                You are right @Kinyera.
If we take 3/2 the answer will be 10.
I think the question is incorrect.
