Hi,

I have been facing issues in certain type of quant questions which is being a major obstacle in acheiving my dream score.

Kindly guide.

1. Certain type of DS questions which have inequality signs. such as is x>0 or any question with inequality in the answer choices as well as in the proving.

I fail to understand what values should i choose in the limited 2 minutes to figure out whether the situation is true/false.

2.In PS Certain type of percentage questions which consist of either tax or some kind of increase or decrease and the answer choices are given in variable terms such as p+r/t+q

I freak out in such questions because each sentence of the problem has something happening. It becomes hard for me to comprehend the problem and solve it in such variables. Kindly guide any easy way to go about such complex questions.

3. The mixing questions.

can hardly solve them.

4. General inequality questions.

Can't figure out the numbers i should choose because there mite be a case where the response comes out false. Many cases can be made.

Kindly guide me fore the above mentioned problems.

further just wanted to enquire out of the sc questions that come up in gmat. About how many can be solved correctly with plain logic. without getting into the technical aspects?

Here are some discussions on these topics. You will find these helpful.
