## Examples of difficult GMAT questions

Generally GMAT quantitative questions are not hard. What makes some of the problems difficult is the way they are asked. The data sufficiency format is not typical for problems of any other standardized test and it requires practice. Most of the problem solving questions are word problems and they could trip some good math students.

(a) 9/16

(b) 1/2

(c) 7/16

(d) 5/16

(e) 3/16

Question: 4 students go to the movies and seat on a row of 4 seats. How many different ways can the 4 students sit?

(c) 26

(d) 18

(e) 16

Question: Is x > 5?
