A. 25%
B. 55%
C. 100%
D. 125%
E. 155%
OA D
Aside: We can think of percent greater than and percent increase as the same:
So, percent greater than = (100)(bigger value - smaller value)/(smaller value)
= (100)(181 - 79)/(79)
= (100)(102/79)
Since the answer choices are relatively spread apart, we can use a little bit of approximation to get:
≈(100)(100/80)
≈(100)(5/4)
≈(100)(1.25)
≈125
Answer: D
