    41% of the passengers on the plane are men. 36% of them are women and 11% of them are boys. The remaining 30 passengers are girls. How many passengers are on the plane?

    Add up the percents:
    41% + 36% + 11% = 88%

    This means that (100% - 88% = 12%) are girls.

    So if the total amount of passengers on the plane is p, we write 12% s 0.12, and we have:
    0.12p = 30

    Type this equation into our search engine, and we get:
    p = 250
