NUST NET Mathematics — Matrices and Determinants
Matrices and Determinants is part of the FSc Mathematics course that NUST NET-Engineering draws on (Mathematics is 100 of the 200 MCQs). It breaks into 4 subtopics, and we hold 106 NET-pattern practice MCQs on it, each with a written explanation. Tap a subtopic below to practise just that.

Matrices and Determinants MCQs from the NET-pattern papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · NUST NET Past Paper 07 · Matrices and Determinants
The determinant of the matrix [[2, 3], [4, 5]] is:
- A.2
- B.−2
- C.22
- D.−22
Show answer
Answer: B. −2 — |2 3; 4 5| = 2·5 − 3·4 = −2.
- Q2 · NUST NET Past Paper 08 · Matrices and Determinants
If A is a 2 × 3 matrix, then its transpose Aᵀ has order:
- A.3 × 2
- B.2 × 3
- C.3 × 3
- D.2 × 2
Show answer
Answer: A. 3 × 2 — Transposing swaps rows and columns: 2 × 3 → 3 × 2.
- Q3 · NUST NET Past Paper 05 · Matrices and Determinants
A square matrix A is called symmetric if:
- A.A = −Aᵀ
- B.A = Aᵀ
- C.A = A⁻¹
- D.A² = A
Show answer
Answer: B. A = Aᵀ — Symmetric means A equals its own transpose.
