The price of fuel decreases by 25%, 15% and 45% in three successive months, but increases by 65% 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: A
Explanation
The correct answer is option 1 i.e. Decreases by 42.14%.
Let the initial price is 100
= 100 × (75/100) × (85/100) × (55/100) × (165/100)
= 57.86%
So, percentage change = (100 - 57.86) / 100 × 100 = 42.14% (Decrease)
