You have a large container of mustard oil. You have used 480 quarts of oil. Seventy - Six percent of mustard oil remains. How many quarts of mustard oil remain?

You would have 240 quarts of mustard remaining.

If I used 480 quarts of oil and 76% still remains, it means that I used 100% - 76% = 24% of the oil.

So we know that 480 quarts are as much as 24% of an unknown number. We can write it down as:

480 = 24% from x

480 = 24/100x / * 100 (both sides)

48 000 = 24x / : 24 (both sides)

x = 2000

So there are 2000 quarts in the oil. We used 480 of them, so there's still remaining 2000 - 480 = 1520 quarts.
