The graph shows the petroleum reserves that remain in five regions of Europe. Arrange the regions by decreasing amount of petroleum reserves

B>A>C>D>E

Explanation:

The graph in the question shows the amount of petroleum reserves (on y-axis) in five regions of Europe (on x-axis). To arrange the amount of reserves in a decreasing order, this means we arrange from the most amount to the least amount of petroleum reserves (million of barrels of oil equivalent).

The height of the the bar graph represents the amount of petroleum reserves in each region. Hence, the tallest and shortest bar represents the most and least respectively.

According to the graph in the image, Region B has the most amount of petroleum reserves. Region A is next to it. Region C follows A. Region D follows and the least amount is Region E. Based on this, the descending or decreasing order is:

B>A>C>D>E
