Sample NUST NET (Engineering) MCQs with answers 12 questions

12 questions from the test, one or two from each chapter. Try each one, then open the answer.

1. A complex number z satisfies z + z̄ = 6 and z − z̄ = 8i. The value of |z| is

  1. A
    5
  2. B
    10
  3. C
    7
  4. D
    25
Show answer

Answer: A. If z = x + iy, then z + z̄ = 2x = 6 and z − z̄ = 2iy = 8i, so z = 3 + 4i and |z| = √(9 + 16) = 5. Forgetting the factor 2 gives z = 6 + 8i and |z| = 10.

2. The value of the determinant with rows [1 2 3], [4 5 6] and [2 4 6] is

  1. A
    0
  2. B
    6
  3. C
    −6
  4. D
    12
Show answer

Answer: A. The third row is 2 times the first row. A determinant with two proportional rows is 0, so no expansion is needed.

3. The real solutions of (x + 1)(x + 2)(x + 3)(x + 4) = 24 are

  1. A
    0 and 5
  2. B
    −1 and −4
  3. C
    1 and −6
  4. D
    0 and −5
Show answer

Answer: D. Pair the outer and inner factors: (x2 + 5x + 4)(x2 + 5x + 6) = 24. With y = x2 + 5x this is y2 + 10y = 0, so y = 0 (x = 0 or −5) or y = −10, and x2 + 5x + 10 = 0 has no real roots.

4. For |x| < 1/3, the first three terms of the expansion of (1 + 3x)1/3 are

  1. A
    1 + x − x2
  2. B
    1 + x + x2
  3. C
    1 + x − 2x2
  4. D
    1 − x + x2
Show answer

Answer: A. (1 + y)1/3 = 1 + y/3 + [(1/3)(−2/3)/2!]y2 = 1 + y/3 − y2/9. With y = 3x this is 1 + x − x2; forgetting the 2! gives −2x2.

5. For events A and B, P(A) = 0.5, P(B) = 0.4 and P(A ∩ B) = 0.2. The probability that neither A nor B occurs is

  1. A
    0.1
  2. B
    0.7
  3. C
    0.8
  4. D
    0.3
Show answer

Answer: D. P(A ∪ B) = 0.5 + 0.4 − 0.2 = 0.7, so P(neither) = 1 − 0.7 = 0.3. Forgetting to subtract P(A ∩ B) gives 1 − 0.9 = 0.1.

6. The exact value of tan 15° is

  1. A
    2 + √3
  2. B
    2 − √3
  3. C
    √3 − 1
  4. D
    (√6 − √2)/4
Show answer

Answer: B. tan(45° − 30°) = (1 − 1/√3)/(1 + 1/√3) = (√3 − 1)/(√3 + 1) = (√3 − 1)2/2 = 2 − √3. 2 + √3 is tan 75°, and (√6 − √2)/4 is sin 15°.

7. f(x) = (x2 − 9)/(x − 3) for x ≠ 3, and f(3) = k. f is continuous at x = 3 when k equals

  1. A
    6
  2. B
    0
  3. C
    3
  4. D
    9
Show answer

Answer: A. For x ≠ 3, f(x) = x + 3, so the limit at x = 3 is 6. Continuity needs f(3) to equal this limit, so k = 6.

8. The nth derivative of y = e3x is

  1. A
    n e3x
  2. B
    3n e3x
  3. C
    3n e3x
  4. D
    e3x/3n
Show answer

Answer: C. Each differentiation multiplies by 3: 3e3x, 9e3x, 27e3x, …, so the nth derivative is 3ne3x. Dividing by 3n is what repeated integration does.

9. The area under y = ex from x = 0 to x = ln 3 is (in square units)

  1. A
    3
  2. B
    ln 3
  3. C
    2
  4. D
    e3 − 1
Show answer

Answer: C. ∫0ln 3 ex dx = eln 3 − e0 = 3 − 1 = 2. Forgetting the lower limit gives 3.

10. The directrices of the ellipse x2/25 + y2/9 = 1 are

  1. A
    x = ±25/4
  2. B
    x = ±4
  3. C
    y = ±25/4
  4. D
    x = ±15/4
Show answer

Answer: A. c = √(25 − 9) = 4, so e = 4/5 and the directrices are x = ±a/e = ±5 ÷ (4/5) = ±25/4. The lines x = ±4 pass through the foci.

11. The magnitude of the vector 2i − 3j + 6k is

  1. A
    5
  2. B
    √11
  3. C
    7
  4. D
    49
Show answer

Answer: C. √(22 + (−3)2 + 62) = √(4 + 9 + 36) = √49 = 7. The value 49 forgets the square root.

12. The coulomb, the SI unit of electric charge, expressed in SI base units is

  1. A
    A s−1
  2. B
    A s
  3. C
    A−1 s
  4. D
    kg A s−2
Show answer

Answer: B. Charge = current × time, so 1 C = 1 A × 1 s = 1 A s. A s−1 would be current divided by time, which is not charge.
