A father's age is twice the sum of the ages of his four sons. In 30 years, the total of the sons' ages will be twice the age of their father. How old is the father now? a) 24 b) 48 c) 32 d) 40 e) 36 - ANS d) 40 If the sum of the four son's ages is x at present, the father's age is 2x. In 30 years, the total of the son's ages will be x+4×30=x+120, whereas the father's age will be 2x+30. Therefore, x+120=2(2x+30), which yields x=20, and hence, the father's age at present i...
