a. 24

c. 28
d. 31
e. 43
b
Let the original price = 100.
Price increased by 24% = 100 + 24% of 100 = 124.
Since the final price is 55% greater than the original price, the final price = 100 + 55% of 100 = 155.
p = percent increase from 124 to 155 = Difference/Smaller * 100 = (155-124)/124 * 100 = 25.
The correct answer is
B.
