# XII_Maths_Matrices_1 online Test

Consider the set A of all determinants of order 3 with entries 0 or 1 only. Let B be the subset of A consisting of all determinants with value 1. Let C be the subset of A consisting of all determinants with value –1. Then
C is empty
B has as many elements as C
A = B ( C
B has twice as many elements as elements as C
If A and B are square matrices of equal degree, then which one is correct among the following?
A +B =B+A
A+B =A+B
A-B =B-A
AB =BA
The parameter, on which the value of the determinant  does not depend upon is
a
p
d
x
Normal type of MCQ with one correct option A square matrix A is called idempotent if
A2 = I
A2 = O
2A = I
A2 = A

an invertible matrix
an idempotent matrix
a nilpotent matrix
none of these
Normal type of MCQ with one correct option If A and B are symmetric matrices of the same order, then
AB is symmetric matrix
A(B is a skew-symmetric matrix
AB + BA is a symmetric matrix
AB ( BA is a symmetric matrix
/
A,B
B
C,D
A,B & D

(a2+b2c2)
(ab+bc+ac)
a2+b2 - c2
(a-c)(b-c).

Both A and R are true and R is correct explanation of A
Both A and R are true and R is not correct explanation of A
A is true, R is false
A is false, R is true

Description:

This test consist of 10 questions.Students should ideally take 10 minutes to complete the test. This test is useful for those students who are preparing for IIT JEE, AIEEE or any other engineering entrance test. This test consist of questions from Matrices which, in general, is focused in AIEEE and IIT JEE. Last year 3 questions asked from this chapter in AIEEE. In Matrices, Elementary operations and transpose of matrix are key topics and mostly application based questions are asked.
