Ages of three brothers

by snigdha.singh16 » Sat May 05, 2012 9:39 am
What are the ages of three brothers?

1)The product of their ages is 21
2)The sum of their ages is not divisible by 3


The answer is E

Question - In such type of questions, where ages are considered - do we assume that the ages are not integers? unless it is mentioned ?

Ages can be fractions as well. One will be half an year old after six months of his/her birth!!! :lol:

In all of the age-related questions I've seen, we are only concerned with integers.
