  1. A bank offers a loan of $15,000 at 8% simple interest per annum. What is the total amount repayable after 3 years?

    Answer: $18,600

    Simple interest = 15000 × 0.08 × 3 = $3,600; total = $15,000 + $3,600 = $18,600.

  2. A pipe fills a tank in 6 hours and another empties it in 9 hours. If both are open, in how many hours will the tank be full?

    Answer: 18 hours

    Net rate = 1/6 − 1/9 = 1/18 per hour, so the tank fills in 18 hours.

  3. The ratio of two numbers is 3:5 and their LCM is 120. What is their HCF?

    Answer: 8

    Let the numbers be 3k and 5k; LCM = 15k = 120, so k = 8; HCF = k = 8.

  4. A shopkeeper marks goods 40% above cost and allows a 20% discount. What is his profit percentage?

    Selling price = 1.4 × 0.8 = 1.12 times cost, giving a 12% profit.

  5. If 15 workers can complete a job in 12 days, how many workers are needed to finish the same job in 9 days?

    Answer: 20

    Total work = 15 × 12 = 180 man-days; workers needed = 180 / 9 = 20.

  6. A sum doubles itself at simple interest in 10 years. What is the annual rate of interest?

    Answer: 10%

    For a sum to double in 10 years at SI: 100 = R × 10, so R = 10%.

  7. The average salary of 20 employees is $4,500. If the manager's salary of $9,000 is added, what is the new average?

    Answer: $4,714
