Q1 · Difficulty 1/3
Simplify 3a + 5a.
- 8a
- 8a²
- 15a
- 2a
Show answer & explanation
✓ Answer: A — 8a
Add the like terms: 3a + 5a = 8a.
Q2 · Difficulty 1/3
What is the next term in the sequence 3, 7, 11, 15, ...?
- 19
- 18
- 20
- 17
Show answer & explanation
✓ Answer: A — 19
The common difference is 4, so 15 + 4 = 19.
Q3 · Difficulty 1/3
Solve (x − 3)(x + 2) = 0.
- x = 3 or x = −2
- x = −3 or x = 2
- x = 3 or x = 2
- x = −3 or x = −2
Show answer & explanation
✓ Answer: A — x = 3 or x = −2
Set each bracket to zero: x − 3 = 0 gives x = 3; x + 2 = 0 gives x = −2.
Q4 · Difficulty 1/3
What is the result of rationalising the denominator of 1/√5?
- √5/5
- 1/5
- 5/√5
- √5
Show answer & explanation
✓ Answer: A — √5/5
Multiply numerator and denominator by √5: (1 × √5)/(√5 × √5) = √5/5. Option B forgets to keep √5 in the numerator. Option D incorrectly removes the denominator entirely.
Q5 · Difficulty 1/3
What is the formula for the circumference of a circle with diameter d?
- C = πr²
- C = 2πr²
- C = πd
- C = πd²
Show answer & explanation
✓ Answer: C — C = πd
The circumference of a circle is found using C = πd, where d is the diameter. Alternatively, since d = 2r, this can be written as C = 2πr. The formula C = πr² gives the area, not the circumference.
Q6 · Difficulty 1/3
A tree diagram is drawn for two events A and B. Which expression correctly gives P(A and B)?
- A) P(A) + P(B)
- B) P(A) × P(B | A)
- C) P(B) × P(A | B) + P(A)
- D) P(A) + P(B) − P(A or B)
Show answer & explanation
✓ Answer: B — B) P(A) × P(B | A)
The multiplication rule states P(A and B) = P(A) × P(B | A), which is equivalent to multiplying along the branches of a tree diagram. Option A is the addition rule for mutually exclusive events and does not give the intersection.
Q7 · Difficulty 1/3
If t = 5, find 100 − 10t.
- 50
- 60
- 40
- 90
Show answer & explanation
✓ Answer: A — 50
100 − 10 × 5 = 100 − 50 = 50.
Q8 · Difficulty 1/3
What is the common ratio of 3, 6, 12, 24, ...?
- 2
- 3
- 6
- 0.5
Show answer & explanation
✓ Answer: A — 2
Each term is multiplied by 2: 6 ÷ 3 = 2.
