In this post, we present some sample objective type questions that can be asked in the higher secondary mathematics examination. There are a total of 40 one mark questions divided into sets of 8. It is really worth giving a good practice on these questions as this would equip the candidate well for the final examination.

1) If A =

then the value of AA^{T} is

a) 3

b) 0

c) 1

d) 2

2) If the matrix

has an inverse then the values of K

a) k is any real number

b) k = -4

c) k ≠ -4

d) k ≠ 4

3) If the equation -2x+y+z=l, x-2y+z=m, x+y-2z=n such that l+m+n=0, then the system has

a) a non-zero unique solution

b) trivial solution

c) Infinitely many solutions

d) No Solution

4) Which of the following is not true regarding the non-singular matrices A, B

a) A (adj A) = (adj A) A

b) (AB)^{-1}= B^{-1}A^{-1}

c) (AB)^{T} = B^{T}A^{T}

d) (A^{T})^{-1}≠ (A^{-1})^{T}

5) If and are two unit vectors and ϴ is the angle between them, then ( + ) is a unit vector if

a) ϴ=��/3 b) ϴ=��/4 c) ϴ=��/2 d) ϴ=2��/3

6) The shortest distance of the point (2,10,1) from the plane .(3 - + 4 ) = 2 is

a)

b)

c) 2

d)

7) If the magnitude of moment about the point + of a force + a - acting through the point + is then the value of a is

a) 1

b) 2

c) 3

d) 4

8) If the points (3, 2, - 4), (9, 8, - 10) and ($, 4, - 6) are collinear then $ is

a) 5

b) -5

c) 5/2

d) 10
