Mathematics - Matrices
Practise 19 BITSAT previous year questions on Matrices, compiled from papers spanning 2009 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty BITSAT tests.
Matrices has been asked in 11 of the 16 years of BITSAT papers analysed (2009–2024), with 19 questions in all. 47% of them were easy, 53% moderate and 0% tough. Most of its questions came from 2024, with 5 questions that year. In the last three years (2022–2024) it had 9 questions across 6 papers, about 1.5 per paper.
The chapter's 6 topics are not weighted equally: Product of Matrices (6 questions, 32%), Inverse of a Matrix (4 questions, 21%), and Adjoint and its Properties (3 questions, 16%) have been asked the most. Over the last five years the most frequent topics have been Inverse of a Matrix (3), Basic Algebra of Matrices (2), and Product of Matrices (2).
