BPP Mathematics 5 — Questions and Answers
Question 1: What is the median of the data set: 4, 7, 2, 9, 1, 5, 8?
- 4
- 5 (Correct answer)
- 6
- 7
Correct answer: 5
Sorted: 1, 2, 4, 5, 7, 8, 9; the middle value (4th of 7) is 5.
Question 2: Simplify: (15x³y²) / (5x²y)
- 3xy (Correct answer)
- 10xy
- 3x²y
- 10x²y
Correct answer: 3xy
15/5 = 3, x³/x² = x, y²/y = y, so the result is 3xy.
Question 3: Two angles of a triangle measure 55° and 78°. What is the third angle?
- 37°
- 42°
- 47° (Correct answer)
- 52°
Correct answer: 47°
Third angle = 180° - 55° - 78° = 47°.
Question 4: What is the least common multiple (LCM) of 8 and 12?
- 16
- 20
- 24 (Correct answer)
- 48
Correct answer: 24
The LCM of 8 and 12 is 24, since 24 = 8 × 3 = 12 × 2.
Question 5: Which of the following is the equation of a line with slope -3 and y-intercept 7?
- y = 3x + 7
- y = -3x - 7
- y = -3x + 7 (Correct answer)
- y = 7x - 3
Correct answer: y = -3x + 7
Using slope-intercept form y = mx + b: y = -3x + 7.
Question 6: A bag has 4 red and 6 blue chips. Two chips are drawn without replacement. What is the probability both are red?
- 2/15 (Correct answer)
- 4/25
- 1/6
- 2/25
Correct answer: 2/15
P = (4/10) × (3/9) = 12/90 = 2/15.
Question 7: What is the value of the expression: 5 + 3 × (8 - 2)² ÷ 9?
- 13
- 17 (Correct answer)
- 12
- 11
Correct answer: 17
PEMDAS: (8-2)² = 36; 3 × 36 ÷ 9 = 12; 5 + 12 = 17.
