  1. A pipe fills a tank in 10 hours and another empties it in 15 hours. If both are open simultaneously, in how many hours will the tank be filled?

    Answer: 30

    Net rate = 1/10 − 1/15 = 1/30, so the tank fills in 30 hours.

  2. If the area of a square is 144 sq ft, what is its perimeter?

    Answer: 48 ft

    Side = √144 = 12 ft; perimeter = 4 × 12 = 48 ft.

  3. A car depreciates by 10% every year. If its current value is $18,000, what will it be worth after 2 years?

    Answer: $14,580

    Value after 2 years = 18000 × (0.9)² = 18000 × 0.81 = $14,580.

  4. The LCM of 12 and 18 is:

    Answer: 36

    LCM(12, 18) = 36 since 36 is the smallest number divisible by both 12 and 18.

  5. If x + y = 10 and x − y = 4, what is the value of x?

    Answer: 7

    Adding the equations: 2x = 14, so x = 7.

  6. What is 35% of 280?

    Answer: 98

    35% of 280 = 0.35 × 280 = 98.
