Question 41

A

-5.3

B

0.5

C

3

D

8

The minimum value is the lowest value of the curve on y axis which gives a value of -5.3

Correct option:
A

Question 42

A

-1 1\(\frac{1}{2}\)

B

-1

C

1

D

5

log\(_2\) 8 log\(_3\) \(\frac{1}{9}\)

= log \(_2\) 2\(^3\) log\(_3\) 9\(^{-1}\)

= log\(_2\) 2\(^3\) log\(_3\) 3\(^{-2}\)

Based on law of logarithm

= 3 log\(_2\) 2 (-2 log\(_3\) 3)

But log\(_2\) 2 = 1,

log\(_3\) 3 = 1

So, = 3 + 2

= 5

Correct option:
D

Question 43

A

Second only

B

Third only

C

Fourth only

D

First and third only

First quadrant: Sin, Cos and Tan are all positive

Second quadrant: Sin is positive, Cos is negative and Tan is negative

Third quadrant: Tan is positive, Sin is negative and Cos is negative

Fourth quadrant: Cos is positive, Sin is negative and Tan is negative

The correct option is the third quadrant only where Tan is positive and Sin is negative

Correct option:
B

Question 44

D

50

The total number of students is f = 3 + 4 + 5 + 6 + 7 + 6 + 5 + 4

= 40

Correct option:
B

Question 45

A = (p, q, r, t, u, v)

B = (r, s, t, u)

A U B = Elements in both A and B = (p, q, r, s, t, u, v)

(A U B)1 = elements in the universal set E but not in (A U B)= (w, x, y, z)

n(A U B) 1 = number of the elements in (A U B)1 = 4

Correct option:
C

Question 46

A

A straight line of length 4cm

B

a circle of radius 4cm

C

perpendicular to point P at 4cm

D

a circle of diameter 4cm

Locus is the path traced at by a point which moves in accordance with a certain law. It is also the set of all possible position occupied by an object The path traced from all possible location of 4cm from a given point P form a circle of radius 4cm with centre P.

Correct option:
B

Question 47

A

14\(^o\)

B

21\(^o\)

C

32\(^o\)

D

39\(^o\)

Sin(5x - 28) = Cos(3x - 50)..i

But Sin = Cos(90 - )

So Sin(5x - 28) = Cos(90 - [5x - 28])

Sin(5x - 28) = Cos(90 - 5x + 28)

Sin(5x - 28) = Cos(118 - 5x)ii

Combining i and ii

Cos(3x - 50) = Cos(118 - 5x)

3x - 50 = 118 - 5x

Collecting the like terms

3x + 5x = 118 + 50

8x = 168

x = \(\frac{168}{8}\)

x = 21\(^o\)

Answer is B

Correct option:
B

Question 48

A

20

B

19

C

17

D

15

Prime numbers are numbers that has only two factors (i.e 1 and itself). They are numbers that are only divisible by 1 and their selves. First four Prime numbers greater than 10 are 11, 13, 17 and 19

Average = sum of numbers / number

= \(frac{(11 + 13 + 17 + 19)}{4}\)

= \(\frac{60}{4}\)

= 15

Correct option:
D

Question 49
