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?

Solution

If the price of crude oil at the end of Friday was ₹44,800 per barrel.

price of crude oil at the end of Thursday of (100+12)% = 44,800

price of crude oil at the end of Thursday of 112% = 44,800

price of crude oil at the end of Thursday = $$\frac{44,800}{112}\times\ 100$$

= $$\frac{44,800}{112}\times\ 100$$

= 40000
