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 ?                          [Bank P.O 1990]
A. 32 years B. 36 Years
C. 40 Years D. 48 Years

Answer: Option C
Explaination:

 


Let the mother's present age be x years.Then, the person's present age = (2/5 x) years.

= 1/2(x+8)

= 2(2x+40)

=5(x+8)

= 40 years.
