Q1. Roman numerals do NOT have a symbol for:
- one thousand
- ten
- zero
- five
Show the answer
Answer: C. zero
Roman numerals (I, V, X, L, C, D, M) have no zero and no place value.
Q2. Which is the largest number?
- 9.9 × 10³
- 1 × 10⁻⁶
- 9 × 10⁴
- 2 × 10⁵
Show the answer
Answer: D. 2 × 10⁵
Compare the powers of 10 first: 10⁵ is the highest power.
Q3. A/an binary relation from A to B is:
- a pair of elements (a, b) in which the order matters
- the set of all first elements of its ordered pairs
- the set of all ordered pairs (a, b) with a ∈ A and b ∈ B
- any subset of A × B
Show the answer
Answer: D. any subset of A × B
Binary relation from A to B: any subset of A × B.
Q4. The LCM of 6x²y² and 14x³y² is:
- 42x³y²
- 84x³y²
- 2x²y²
- 42x²y²
Show the answer
Answer: A. 42x³y²
LCM: lowest common multiple of the numbers (42) and the highest power of each variable.
Q5. The maximum or minimum value of a linear objective function over a bounded feasible region occurs at:
- the centre of the region
- a corner (vertex) point of the region
- the origin only
- any point outside the region
Show the answer
Answer: B. a corner (vertex) point of the region
This is the corner-point principle used in linear programming.
Q6. The exact value of cos 90° is:
- 1
- 0
- √3
- 1/√3
Show the answer
Answer: B. 0
درست جواب: «0»۔ cos 90° = 0.
