Question 991837
lets solve this question intuitively:

Given:
Current age of Karyn : 14 years
Current age of her father : 33 years.

to find :

In how many years will Karyn be half as old as her father?

so when Karyn is 14, her dad is 33 years
                 15,            34       
                 16,            35 
                 17,            36
                 18,            37
                 19,            38-there you go
in 5 iterations you have your answers, hence 5 years is the answer :)
