All WAEC Mathematics past questions

  1. Question 1

    Linear equations

    Solve for $x$: $4x + 10 = 18$.

    1. Option A: x = 2
    2. Option B: x = 3
    3. Option C: x = 1
    4. Option D: x = 7
    Show the answer to question 1

    Answer: A, x = 2

    Subtract 10 from both sides to get 4x = 8, then divide by 4: x = 2.

  2. Question 2

    Probability

    A bag contains 5 red, 7 blue, and 9 green balls. A ball is picked at random. What is the probability that it is blue?

    1. Option A: $\frac{5}{21}$
    2. Option B: $\frac{1}{3}$
    3. Option C: $\frac{3}{7}$
    4. Option D: $\frac{1}{2}$
    Show the answer to question 2

    Answer: B, $\frac{1}{3}$

    There are 7 blue balls out of 21, so the probability is $\frac{1}{3}$.

  3. Question 3

    Simple interest

    Find the simple interest on ₦25,000 for 2 years at 7% per annum.

    1. Option A: ₦3,500
    2. Option B: ₦28,500
    3. Option C: ₦1,750
    4. Option D: ₦7,000
    Show the answer to question 3

    Answer: A, ₦3,500

    I = PRT ÷ 100 = 25,000 × 7 × 2 ÷ 100 = ₦3,500.

  4. Question 4

    Statistics

    Find the mean of 47, 48, 53, 59, 43.

    1. Option A: 51
    2. Option B: 50
    3. Option C: 49
    4. Option D: 48
    Show the answer to question 4

    Answer: B, 50

    The sum is 250 and there are 5 numbers, so the mean is 250 ÷ 5 = 50.

  5. Question 5

    Indices

    Simplify $\frac{x^{7} \times x^{2}}{x^{2}}$.

    1. Option A: $x^{12}$
    2. Option B: $x^{11}$
    3. Option C: $x^{9}$
    4. Option D: $x^{7}$
    Show the answer to question 5

    Answer: D, $x^{7}$

    Add the indices when multiplying and subtract when dividing: 7 + 2 − 2 = 7.
