Sample NECO SSCE Mathematics 2002 questions

1. In the universal set U = {1, 2, ..., 12}, let A be the set of multiples of 2 and B the set of multiples of 3. How many elements are in A intersection B?
  1. 2
  2. 3
  3. 4
  4. 6

Answer: A. 2

The common multiples of 2 and 3 in U are 6 and 12, so there are 2.

2. Evaluate (2^5 x 2^-2) / 2^1.
  1. 2
  2. 4
  3. 8
  4. 16

Answer: B. 4

The index laws give 2^(5 - 2 - 1) = 2^2 = 4.

3. If log base 2 of x equals 5, what is x?
  1. 10
  2. 16
  3. 32
  4. 64

Answer: C. 32

The equation means x = 2^5 = 32.

4. Convert 132 base 4 to base 10.
  1. 24
  2. 26
  3. 28
  4. 30

Answer: D. 30

The value is 1(4^2) + 3(4) + 2 = 30.

5. Simplify 3(2x - 1) - 2(x + 4).
  1. 4x - 11
  2. 4x + 5
  3. 8x - 11
  4. 8x + 5

Answer: A. 4x - 11

Expanding and collecting like terms gives 6x - 3 - 2x - 8 = 4x - 11.
