In the year 2000, barrels of oil consumed is 600 million.
From bar graph, we can see that only Industry (30%) and energy (32%) consume more than 150 million barrel.
600 * 0.3 = 180
600 * 0.32 = 192
Thus, the answer is 2.

We want to find out how many categories in 2000 consumed more than 150 million barrels of oil

First we get total amount of oil consumed in 2000.
It equals 600 million barrels

Then we figure out what percentage does 150 represent from 600.
150/600=1/4=.25

So we just need to find out which of the four categories in 2000 had a percentage consumption greater than 25%.

Only two: Energy and Industry.
