Explanation:
Ages of 3 Brother.
it has to be positive, & should be an integer.
St.1 Product of ages: 21
the possible values is 1,3,7.
21,1,1
Insufficient.
St.2 Sum is not divisible by 3
Multiple value are possible.
Insufficient.
Combined, Still Insuff.

There is nothing stating that the ages have to be different which then increases the possibilities of Statement 1 to
1, 3, 7 OR 21, 1, 1. Insufficient because we have 2 possibilities? rajatchopra1994
Statement 2 is insufficient on its own. Various different numbers that add up to a number that is not-divisible by three.
Taken together we know that the product of the 3 ages has to be 21 and can't be divisible by 3- which then removes the 21, 1, 1 combo. I'm guessing the answer is C ?
