If encounter a question where I need to choose numbers, which numbers should I choose?
Are there numbers which are most suitable?
I have learnt that 0 is that good number to choose from a Kaplan video session.

Suppose there are two numbers such as 10 and 15 given in the question.
Then options which are obtained by simple addition or subtraction of numbers are usually wrong and can be eliminated. So options containing 25 and 5 would be wrong in this case.
Needless to say that we should use these techniques when we have no idea how to solve a question or just have few seconds left in the clock.
