Q1. Geometrically, |z| is:
- the distance of the point z from the origin
- the angle with the x-axis
- the real part
- the area
Show the answer
Answer: A. the distance of the point z from the origin
The correct answer is “the distance of the point z from the origin”. Modulus = distance.
Q2. The discriminant of 4x² − 8x + 1 = 0 is:
- −48
- −24
- 48
- 80
Show the answer
Answer: C. 48
The correct answer is “48”. b² − 4ac = 64 − 16 = 48.
Q3. The determinant of [5 −2 ; 6 −3] is:
- 3
- −27
- 24
- −3
Show the answer
Answer: D. −3
The correct answer is “−3”. |A| = ad − bc = −3.
Q4. A bacterial population of 100 doubles every hour. After 3 hours it is:
- 400
- 600
- 106
- 800
Show the answer
Answer: D. 800
The correct answer is “800”. P = 100 × 2^3.
Q5. The sum of the reciprocals of two consecutive positive integers is 7/12. The integers are:
- 3 and 5
- 3 and 4
- 4 and 5
- 2 and 3
Show the answer
Answer: B. 3 and 4
1/x + 1/(x + 1) = 7/12 gives the positive solution x = 3, so the integers are 3 and 4.
Q6. A person walks 3 km east and then 4 km north. The displacement from the start is:
- 7 km
- 1 km
- 25 km
- 5 km
Show the answer
Answer: D. 5 km
The correct answer is “5 km”. √(3² + 4²) = 5 km.
