The correct answer is C.
Find the factors of 2013:
1, 3, 11, 33, 61, 671, 2013
From all the factors of 2013, only 33 and 61 could be the ages of a father and his son. (The product of two ages should be 2013)
The difference of 61 and 33 is 28 years and this number won’t change in 2015!The Absolute Best Books to Ace Algebra
