All JAMB Mathematics past questions

  1. Question 1

    Statistics

    Find the mean of 2, 4, 6, 8, and 10.

    1. Option A: 5
    2. Option B: 6
    3. Option C: 7
    4. Option D: 30
    Show the answer to question 1

    Answer: B, 6

    The sum is 30 and there are 5 numbers, so the mean is 6.

  2. Question 2

    Linear equations

    Solve for $x$: $4x + 6 = 38$.

    1. Option A: x = 9
    2. Option B: x = 7
    3. Option C: x = 8
    4. Option D: x = 11
    Show the answer to question 2

    Answer: C, x = 8

    Subtract 6 from both sides to get 4x = 32, then divide by 4: x = 8.

  3. Question 3

    Mensuration

    Find the area of a circle of radius 35 cm. (Take $\pi = \frac{22}{7}$.)

    1. Option A: 220 cm²
    2. Option B: 3,850 cm²
    3. Option C: 7,700 cm²
    4. Option D: 110 cm²
    Show the answer to question 3

    Answer: B, 3,850 cm²

    Area = $\pi r^2$ = 22/7 × 35 × 35 = 3,850 cm².

  4. Question 4

    Statistics

    Find the mean of 16, 17, 22, 27, 13.

    1. Option A: 19
    2. Option B: 20
    3. Option C: 18
    4. Option D: 17
    Show the answer to question 4

    Answer: A, 19

    The sum is 95 and there are 5 numbers, so the mean is 95 ÷ 5 = 19.

  5. Question 5

    Quadratic equations

    Solve the equation $x^2 - 5x + 4 = 0$.

    1. Option A: x = -1 or x = -4
    2. Option B: x = -1 or x = 4
    3. Option C: x = 1 or x = 4
    4. Option D: x = 1 or x = -4
    Show the answer to question 5

    Answer: C, x = 1 or x = 4

    The equation factorises as $(x - 1)(x - 4) = 0$, so x = 1 or x = 4.

  6. Question 6

    Percentages

    A trader bought a radio for ₦5,000 and sold it for ₦5,750. Find the percentage profit.

    1. Option A: 15%
    2. Option B: 13%
    3. Option C: 20%
    4. Option D: 30%
    Show the answer to question 6

    Answer: A, 15%

    Profit = ₦750. Percentage profit = 750 ÷ 5,000 × 100 = 15%.
