  1. A student needs 40% to pass. She scores 178 marks and fails by 22 marks. What are the maximum marks?

    500. Pass marks = 178 + 22 = 200, and 200 is 40% of the maximum, so maximum = 200 / 0.40 = 500.

  2. In an election between two candidates, 20% of the 8,000 votes cast were invalid. The winner got 55% of the valid votes. How many valid votes did the loser get?

    2,880. Valid votes = 80% of 8,000 = 6,400. The loser got 100% - 55% = 45% of valid votes: 0.45 x 6,400 = 2,880. The winning margin is 10% of 6,400 = 640.
