Increasing the original price of an item by 15 percent and then increasing the new price by another 15 percent is equivalent to increasing the original price by

A 32.25%
B 31.00%
C 30.25%
D 35.54%

Correct Answer: 32.25%

Let the original price be P. Now, the new price after increasing the original price by 15% = 1.15P The final price after increasing the new price by another 15% = 1.15x1.15P = 1.3225P. So, actual increament in the original price = {1.322P - P) / P} x 100 = 32.25% [Shortcut: + 15 + 15 + (15x15)/100  = 32.25%]
