Simplification questions with solutions

6 from the 146-question pool, worked in full.

  1. 1. What is the value of 60% of 400 divided by 30% of 80?

    • A. 12
    • B. 8
    • C. 15
    • D. 10 ✓

    Solution. 60% of 400 = 240, and 30% of 80 = 24. So 240 / 24 = 10.

  2. 2. 42% of 250 + 15² ÷ 5 = ?

    • A. 150 ✓
    • B. 145
    • C. 155
    • D. 160

    Solution. 42% of 250 = 105. 15² ÷ 5 = 225 ÷ 5 = 45. 105 + 45 = 150.

  3. 3. Simplify: (81 ÷ 9) + (6 × 7) = ?

    • A. 51 ✓
    • B. 49
    • C. 53
    • D. 55

    Solution. (81 ÷ 9) = 9 and (6 × 7) = 42. So 9 + 42 = 51.

  4. 4. What is the value of √196 + √169?

    • A. 25
    • B. 27 ✓
    • C. 26
    • D. 28

    Solution. √196 = 14 and √169 = 13, so their sum is 14 + 13 = 27.

  5. 5. Simplify: 15 + 6 ÷ 3 × 2 − 4

    • A. 15 ✓
    • B. 17
    • C. 11
    • D. 19

    Solution. By BODMAS: 6 ÷ 3 = 2, then 2 × 2 = 4. So 15 + 4 − 4 = 15.

  6. 6. Evaluate: 64 ÷ 8 × 5.

    • A. 40 ✓
    • B. 42
    • C. 38
