请问答案c是怎么算出来的？ 多谢。

Q28:

In 1994, Kenneth’s annual salary was 30 percent higher than it was in 1993. In 1995, Kenneth’s annual salary was reduced to 104 percent of his 1993 annual salary. Kenneth’s 1995 annual salary was what percent less than his 1994 annual salary?

A. 16%

B. 20%

C. 24%

D. 26%

E. 28%

假设1993的是1

则1994：（1＋0.3)＝1。3

1995：1。04

所以要求的答案是（1。3－1。04）/1.04=26/104

就是轻微少于26％（因为分母大于100），但是大于20％（因为26乘以5大于104），所以选c

分母不是除以94年的annual salary吗？ （1。3－1。04）/1.3？因为问的是than his 1994 annual salary啊？谢谢
