The price of fuel decreases by 25%, 10% and 30% in three successive months, but increases by 60% 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: B

Explanation

The correct answer is Option 2 i.e. Decreases by 24.4%.

Let the orginal price is 100

100 × (100−25)100\frac{(100-25)}{100} × (100−10)100\frac{(100-10)}{100} × (100−30)100\frac{(100-30)}{100} × (100+60)100\frac{(100+60)}{100}

⇒ 75 × 0.9  × 0.7 × 1.6

⇒ 75.6%

Now compare with original price 100 → final is 75.6

Decrease = 100 – 75.6 = 24.4%
