A shopkeeper increases the price of an item first by 8% and then by 5%. What is the total percentage increase?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e 13.4%.
Total increase (%) = a + b + (a × b) / 100
Total increase = 8 + 5 + (8 × 5) / 100 = 13 + 40 / 100 = 13 + 0.4 = 13.4%
