  1. A can complete a work in 10 days and B in 15 days. In how many days can they complete it together?

    Answer: 6 days

    Combined rate = 1/10 + 1/15 = 1/6, so they finish the work in 6 days.

  2. If the cost price of 10 items equals the selling price of 8 items, what is the profit percentage?

    Answer: 25%

    Let CP per item = 1; then SP per item = 10/8 = 1.25, giving profit = 25%.

  3. A sum of money doubles itself in 8 years at simple interest. What is the rate of interest per annum?

    Answer: 12.5%

    When money doubles, SI = P; R = (100 × P)/(P × 8) = 12.5%.

  4. Find the LCM of 12, 18, and 24.

    Answer: 72

    LCM(12, 18, 24) = 2³ × 3² = 72.

  5. The average of 5 consecutive even numbers is 30. What is the largest number?

    Answer: 34

    The middle (3rd) number equals the average = 30, so the five numbers are 26, 28, 30, 32, 34 and the largest is 34.

  6. A 20% discount on a marked price gives $80 off. What is the marked price?

    Answer: $400

    Marked price = 80 ÷ 0.20 = $400.
