  1. The simple interest on $5,000 at 8% per annum for 3 years is:

    Answer: $1,200

    SI = P × R × T / 100 = 5000 × 8 × 3 / 100 = $1,200.

  2. A cube has a volume of 125 cm³. What is the total surface area of the cube?

    Answer: 150 cm²

    Side = ∛125 = 5 cm; surface area = 6 × 5² = 150 cm².

  3. In a coding system, APPLE is coded as BQQMF. How is MANGO coded?

    Answer: NBOHP

    Each letter is shifted forward by 1 in the alphabet, so M→N, A→B, N→O, G→H, O→P = NBOHP.

  4. A clock shows 3:15. What is the angle between the hour and minute hands?

    Answer: 7.5°

    At 3:15, minute hand is at 90°; hour hand is at 90+15×0.5 = 97.5°; angle = 7.5°.

  5. If ΔABC ∼ ΔDEF and AB:DE = 2:3, then the ratio of their areas is:

    Answer: 4:9

    The ratio of areas of similar triangles equals the square of the ratio of corresponding sides: (2/3)² = 4/9.

  6. A sequence follows the rule: each term = sum of the two preceding terms. If the 5th term is 12 and the 6th term is 20, what is the 4th term?

    Answer: 8

    6th = 5th + 4th → 20 = 12 + 4th → 4th = 8.

  7. If 2x + 3y = 12 and 3x + 2y = 13, then x + y = ?

    Answer: 5

    Adding both equations: 5x + 5y = 25 → x + y = 5.
