The following bar graph shows the percentage increase in the price of crude oil on different days of a given week compared to its price on the previous day.
If the price of crude oil at the end of Friday was ₹44,800 per barrel, then what was the price (per barrel) of crude oil at the end of Thursday?
Answer & explanation
Correct answer: option 4
Let price of crude oil at end of Thursday = 100x
Price of crude oil at end of Friday = 100x + 12% of 100x = 112x
According to question ,
112x = 44800
x = 400
100x = 100 × 400 = 40000
So , price of crude oil at the end of Thursday = 40000
