Q). (log9 ) log10 0.01 =
A) (7/8)1
B) (7/16)0
C) (1/16)-2
D) (1/8)2

Explanation: A, B, C, D

Q). Exponential form of log464 = 3 is
A) 34 = 64
B) 43 = 64
C) 42 = 81
D) None

C) 42 = 81
Explanation: log464 = 3 ⇒ 43 = 64

Q). =
A) 1
B) 3
C) 5
D) 6

C) 5
Explanation: Let x = X = ⇒ x2 = 20+x
x2 -x – 20 = 0 => x2 – 5x + 4x – 20 = 0
x(x-5) + 4(x-5) = 0=> (x-5) (x + 4) = 0
=> x = 5

Q). From the following Venn-diagram B – A =……………………. A) {1,2, 3}
B) {4, 5}
C) {6, 7}
D) None

C) {6, 7}
Explanation: From the Venn-diagram
B -A = {4,5,6,7} -{1, 2,3,4,5}
= {6, 7}

Q). If A = {a, b, c, d}, then the number of subsets for A is …………………….
A) 5
B) 6
C) 16
D) 65

C) 16
Explanation: Given A = {a, b, c, d} => n(A) = 4

No. of subsets = 2n = 24 = 16

Q). If α,β,ɣ are the zeroes of the polynomial
f(x) = ax3 + bx2 + cx + d, then A) 1/d
B) 1/c
C) c/d
D) –c/d

D) –c/d
Explanation: Given f(x) = ax3 + bx2 + cx + d
= = = =-c/d

Q). A quadratic polynomial whose zeroes are 5 and -2 is ………………
A) x2 + 5x-2
B) x2 + 3x-10
C) x2-3x-10
D) x2-2x + 5

C) x2-3x-10
Explanation: α = 5 β = -2
x2 – (α + β) X + αβ = 0
⇒ x2 – (5 – 2) x + 5 (-2) = 0
⇒ x2-3x-10 = 0

Q). The lines represented by 5x + 7y – 14 = 0 and 10x + 3y – 8 = 0 are…….. lines.
A) Coincident
B) Vertical
