WAEC Past Questions from Repeated Topics
Here are real examples of the types of questions that WAEC repeats regularly:
1. Number Base Conversion
Convert 101011₂ to base 10.
(WAEC June 2021)
Solution:
= 1×2⁵ + 0×2⁴ + 1×2³ + 0×2² + 1×2¹ + 1×2⁰ = 43₁₀
2. Simple Interest
A man invested ₦20,000 at 5% per annum for 3 years. Calculate the simple interest.
(WAEC June 2022)
Solution:
SI = (P × R × T) / 100
= (20,000 × 5 × 3)/100 = ₦3,000
3. Quadratic Equation
Solve: x² - 5x + 6 = 0
(WAEC June 2020)
Solution:
(x - 2)(x - 3) = 0 ⇒ x = 2 or 3
4. Mensuration
Find the area of a trapezium with parallel sides 12 cm and 8 cm, and height 5 cm.
(WAEC June 2023)
Solution:
Area = ½ × (a + b) × h
= ½ × (12 + 8) × 5 = 50 cm²
5. Trigonometry
In triangle XYZ, angle Y = 90°, XY = 6 cm, YZ = 8 cm. Find angle Z.
(WAEC June 2021)
Solution:
tan(Z) = 6/8 = 0.75 ⇒ Z ≈ 36.87°
6. Statistics
Find the mean of: 5, 7, 10, 8, 5.
(WAEC June 2022)
Solution:
Sum = 35, Number = 5 ⇒ Mean = 35/5 = 7
7. Probability
A box contains 4 red and 6 blue balls. One is picked randomly. Find the probability of red.
(WAEC June 2020)
Solution:
P = 4 / 10 = 2/5
