Sample Past Questions and Solutions
Practicing past questions is an effective way to familiarize yourself with the exam format and question styles. Here are some sample questions from previous WAEC Mathematics exams:
1. Number Bases
Convert 1011₂ to base 10.
Solution:
1×2³ + 0×2² + 1×2¹ + 1×2⁰ = 8 + 0 + 2 + 1 = 11₁₀
2. Algebra
Solve the equation: 2x + 3 = 7.
Solution:
2x = 7 - 3 → 2x = 4 → x = 2
3. Trigonometry
Find the value of sin 30°.
Solution:
sin 30° = 0.5
4. Statistics
Find the mean of the following numbers: 5, 10, 15, 20, 25.
Solution:
Mean = (5 + 10 + 15 + 20 + 25) / 5 = 75 / 5 = 15
5. Probability
A die is rolled once. What is the probability of getting an even number?
Solution:
Even numbers on a die: 2, 4, 6 → 3 outcomes
Total possible outcomes: 6
Probability = 3/6 = 0.5
Regular practice with such questions enhances problem-solving speed and accuracy.
