A father's and his son's current ages add up to 60 years. Six years ago, the father was five times the son's age. Son's age after 6 years will be:
A. 12 years B. 14 years C. 18 years D. 20 years
Explanation: Let the son and father's current ages be x and (60 -x) years, respectively.As a result, (60 - x) - 6 = 5 (x - 6),x = 5x - 30 = 54,84 = 6x,x equals 14.After 6 years, the age of the son is (x+ 6) = 20 years.
