The price of fuel decreases by 40%, 50% and 15% in three successive months, but increases by 40% in the fourth month. What is the percentage increase/decrease in the price of fuel in the fourth month as compared to its original price?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Decreases by 64.3%.
Original = 100
After decreases:
100 × 0.6 × 0.5 × 0.85 = 25.5
After 40% increase:
25.5 × 1.4 = 35.7
Change from original: 35.7 - 100 = -64.3
Percentage decrease = 64.3%
