Hi
Suryangshu ,
In order to solve assumption questions, you must understand the argument very well.
Following these points:
1. Read the question and determine whether it is an assumption question.
2. Go back to the argument and read slowly, very slowly until you get what it is conveying.
3. Find out the conclusion of the argument.
4. Find out the premise on which this conclusion depends.
5. Try to think about the link between point 3 and 4 above.
6. Start working on POE.(Make sure you have a solid reason of rejecting any answer choice).
7. Finally apply the negation technique to determine whether you are correct.
P.S: I donot agree to go for the Quantity of questions. This way you will end up exhausting your resources with zero results. You should not go to the next question until you are comfortable with the current one.
All the best.
