Solved Mathematics sample Questions and Answers: below are our solved sample past questions to practice with before the exam.

1. Which of these numbers is not less than -2?

  1. -1,
  2. -3,
  3. -4,
  4. -5.
  5. -6

Solution Solving: -2 is greater than -2, -3, -4, -5, -6 and so on. But -1 is greater than -2.

The Correct Answer is A): Because it is greater than -2.

2. -6 is greater than -2 but less than -7? True or false

  1. True
  2. Both
  3. False
  4. None of the above

Solving for the solution: -6 is greater than any number from -7 to the negative infinity but less than any number from -5 to the positive infinity.

The Correct Answer is C): Because -6 is not greater than -2 and it is not less than -7.

3. Add 26b + 12a + 16a – 4b

  1. 22b + 28a
  2. -22b + 28a
  3. 22b – 28a
  4. -22b – 28a

Solution Solving for Questions 3: Firstly, you have to Collect like terms. Therefore, we have;

  • 26b – 4b + 12a + 16a.
  • Next, we have 26b – 4b = 22b
  • And 12a + 16a = 28a
  • Therefore, we have 22b + 28a

The Correct Answer is A): 22b + 28a

4. Multiply this equation: (x – 6)(2x + 7)?

  1. 2×2 + 5x – 42
  2. 2×2 – 5x – 42
  3. 2×2 – 5x + 42
  4. 2×2 + 5x + 42
  5. -2×2 + 5x – 42

Solving for question 4 solution: Here, we start by removing the bracket

Thus; 2×2 + 7x – 12x – 42

Hence, 2×2 – 5x – 42

The Correct Answer is B): 2×2 – 5x – 42

5. Factorise the following: 5×2 – 15x – 20?

  1. 5(x+4)(x+1).
  2. -2(x-4)(x+5)
  3. -5(x+4)(x-1)
  4. 5(x-4)(x+1)

Solution Solving to question 5: Firs find the L.C.M of 5, 15 and 20 = 5(x2 – 3x – 4).

  • = 5(x2 – 4x + x – 4).
  • = 5{x(x – 4) +1(x – 4)}.
  • = 5(x-4)(x+1).

The Correct Answer is D): 5(x-4)(x+1)

We may likely drop the answers if any is available. So keep visiting and refreshing this page to check if we have dropped it. Please, don’t miss out.
