    Preparing for the Joint Admissions and Matriculation Board (JAMB) exams, especially the Mathematics section, can be daunting for many students. Mathematics is a core subject for students aiming for science, engineering, and technology courses in Nigerian universities, so achieving a good score is crucial. This article provides detailed sample questions, solutions, and study tips to help you succeed in the JAMB Mathematics exam.

    JAMB Mathematics Exam

    The Mathematics section in JAMB consists of 40-50 multiple-choice questions, covering topics across algebra, geometry, trigonometry, calculus, probability, and statistics. To ace this exam, it’s essential to understand the structure, key topics, and strategies for efficient problem-solving.


    Sample JAMB Mathematics Questions and Answers

    Below are sample questions, complete with step-by-step solutions to help you understand the method of answering JAMB-style Mathematics questions.

    Question 1: Algebra

    Problem: If 2x+3=72x + 3 = 72x+3=7, what is the value of xxx?

    Solution:

    1. Begin by isolating xxx on one side of the equation: 2x+3=72x + 3 = 72x+3=7
    2. Subtract 3 from both sides: 2x=42x = 42x=4
    3. Divide both sides by 2: x=2x = 2x=2

    Answer: x=2x = 2x=2


    Question 2: Probability

    Problem: A box contains 5 red, 3 blue, and 2 green balls. If a ball is chosen at random, what is the probability that it is blue?

    Solution:

    1. Total number of balls = 5 + 3 + 2 = 10
    2. Number of blue balls = 3
    3. Probability of picking a blue ball = Number of blue ballsTotal number of balls=310\frac{\text{Number of blue balls}}{\text{Total number of balls}} = \frac{3}{10}Total number of ballsNumber of blue balls​=103​

    Answer: 310\frac{3}{10}103​


    Question 3: Geometry

    Problem: The area of a rectangle is 48 cm², and its length is 8 cm. Find its width.

    Solution:

    1. Use the area formula for a rectangle, Area=Length×Width\text{Area} = \text{Length} \times \text{Width}Area=Length×Width.
    2. Plug in the known values: 48=8×Width48 = 8 \times \text{Width}48=8×Width
    3. Divide both sides by 8: Width=488=6 cm\text{Width} = \frac{48}{8} = 6 \text{ cm}Width=848​=6 cm

    Answer: Width = 6 cm


    Question 4: Trigonometry

    Problem: Find the value of sin⁡30∘\sin 30^\circsin30∘.

    Solution:

    1. Knowing the trigonometric values, we have sin⁡30∘=0.5\sin 30^\circ = 0.5sin30∘=0.5.

    Answer: sin⁡30∘=0.5\sin 30^\circ = 0.5sin30∘=0.5


    Question 5: Calculus

    Problem: Differentiate f(x)=3×2+4xf(x) = 3x^2 + 4xf(x)=3x2+4x with respect to xxx.

    Solution:

    1. Using the power rule, differentiate each term: f′(x)=2×3×2−1+4=6x+4f'(x) = 2 \times 3x^{2-1} + 4 = 6x + 4f′(x)=2×3x2−1+4=6x+4

    Answer: f′(x)=6x+4f'(x) = 6x + 4f′(x)=6x+4
