Hey Rag this an easy one.

Hey Rag this an easy one. Don't fret over how the question is worded, just look into the Rules of Prime Numbers that can be applied here

A prime number is a number that can be divided by 1 and itself

Here Q is a prime number divisible by 1 and Q
Remember Q > 10

3Q can be equally divided by 1,3Q ,3 and Q. Apart from 1 the next smallest number is 3 so answer is C
