Q24:
At a certain company, each employee has a salary grade s that is at least 1 and at most 5.Each employee receives an hourly wage p, in dollars, determined by the formula p = 9.50 + 0.25(s – 1).An employee with a salary grade of 5 receives how many more dollars per hour than an employee with a salary grade of 1？
A.$0.50
B.$1.00
C.$1.25
D.$1.50
E.$1.75

答案是C~但是我算了几次都是B~请问是我理解题目有误么？


Q36:
If n is an integer and 100 < n <200, what is the value of n?
(1)n/36 is an odd integer.
(2)n/45 is an even integer.

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.

答案是C，我想了好久还是觉得是B~为什么要两个联起来才可以~明明第二个条件就行了呀~只有n=180的时候，就符合了呀~
