WAEC GCE General Mathematics 2025 Practice Questions and Answers

Here are selected objective and theory questions for effective practice:

SECTION A: Objective Questions

1. Simplify: (2/3) ÷ (4/9)

  • A. 1/6

  • B. 3/2

  • C. 3/4

  • D. 9/8

Solution:
(2/3)÷(4/9)=(2/3)×(9/4)=18/12=3/2(2/3) ÷ (4/9) = (2/3) × (9/4) = 18/12 = 3/2
✅ Correct Answer: B (3/2)

2. If the mean of 5 numbers is 12, find their sum.

  • A. 60

  • B. 65

  • C. 55

  • D. 50

Solution:
Mean = Sum ÷ Number of terms
12 = Sum ÷ 5
Sum = 12 × 5 = 60
✅ Correct Answer: A (60)

3. Solve: If 2x – 5 = 9, find x.

  • A. 2

  • B. 5

  • C. 7

  • D. 6

Solution:
2x – 5 = 9
2x = 14
x = 7
✅ Correct Answer: C (7)

4. A bag contains 3 red, 5 blue, and 2 green balls. If one ball is chosen at random, what is the probability that it is blue?

  • A. 3/10

  • B. 5/10

  • C. 2/10

  • D. 1/10

Solution:
Total balls = 3 + 5 + 2 = 10
Blue = 5
P(blue) = 5/10 = 1/2
✅ Correct Answer: B (5/10 or 1/2)

5. If y = 2x + 5 and x = 3, find y.

  • A. 11

  • B. 15

  • C. 12

  • D. 10

Solution:
y = 2(3) + 5 = 6 + 5 = 11
✅ Correct Answer: A (11)

SECTION B: Theory Questions

1. A man bought 120 oranges at ₦40 per dozen. He sold each orange at ₦5. Calculate:
a. The total cost price
b. The total selling price
c. The profit made

Solution:

  • 1 dozen = 12 oranges → 120 ÷ 12 = 10 dozens

  • Cost price = 10 × ₦40 = ₦400

  • Selling price = 120 × ₦5 = ₦600

  • Profit = ₦600 – ₦400 = ₦200

✅ Answer: Profit = ₦200

2. Find the simple interest on ₦8,000 for 3 years at 5% per annum.

Solution:
SI = (P × R × T) ÷ 100
= (8000 × 5 × 3) ÷ 100
= 1200

✅ Answer: ₦1,200

3. A triangle has sides 6 cm, 8 cm, and 10 cm. Show that it is a right-angled triangle.

Solution:
By Pythagoras Theorem:
Longest side² = Sum of squares of other two sides
10² = 6² + 8²
100 = 36 + 64
100 = 100 ✔

✅ Answer: Yes, it is a right-angled triangle.

4. A car travels at 60 km/h for 2 hours and then at 80 km/h for 1 hour. Find the average speed.

Solution:

  • Distance 1 = 60 × 2 = 120 km

  • Distance 2 = 80 × 1 = 80 km

  • Total distance = 120 + 80 = 200 km

  • Total time = 2 + 1 = 3 hours

  • Average speed = 200 ÷ 3 ≈ 66.7 km/h

✅ Answer: 66.7 km/h

5. The ages of 5 students are 10, 12, 14, 16, and 18. Find:
a. The mean
b. The median
c. The mode

Solution:

  • Mean = (10 + 12 + 14 + 16 + 18) ÷ 5 = 70 ÷ 5 = 14

  • Median = Middle number = 14

  • Mode = No repeating values → No mode

✅ Answer: Mean = 14, Median = 14, Mode = None
