  1. A train 200 m long passes a pole in 10 seconds. How long will it take to pass a platform 300 m long?

    Answer: 25 seconds

    Speed = 200/10 = 20 m/s; time to pass platform = (200+300)/20 = 25 seconds.

  2. What is the compound interest on $5,000 at 10% per annum for 2 years, compounded annually?

    Answer: $1,050

    Amount = 5000 × (1.1)² = 6,050; CI = 6,050 − 5,000 = $1,050.

  3. Two numbers are in the ratio 4:7. If 6 is subtracted from each, the ratio becomes 2:5. Find the larger number.

    Answer: 35

    Let numbers be 4x and 7x; (4x−6)/(7x−6) = 2/5 → x = 5; larger = 7×5 = 35.

  4. A man rows upstream at 6 km/h and downstream at 10 km/h. What is the speed of the current?

    Answer: 2 km/h

    Speed of current = (downstream − upstream) / 2 = (10 − 6) / 2 = 2 km/h.

  5. Find the missing term in the series: 2, 6, 12, 20, 30, ?

    Answer: 42

    Differences are 4, 6, 8, 10, 12; next term = 30 + 12 = 42.

  6. A bank account earns 6% per annum compounded semi-annually. What is the effective annual rate?

    Answer: 6.09%

    EAR = (1 + 0.06/2)² − 1 = (1.03)² − 1 = 0.0609 = 6.09%.

  7. If a : b = 2 : 3 and b : c = 4 : 5, what is a : b : c?

    Answer: 8:12:15

    Scale b to common: a:b = 8:12, b:c = 12:15; combined ratio a:b:c = 8:12:15.
