Direction (1-10): What value should come in place of question mark (?) in the following questions?
1). [(23.65)^2 - (48.35)^2 ] / 0.9 = ?
-1976
-1864
-1724
-1684
None of these
1). Answer: a)
? = [(23.65 + 48.35)(23.65 – 48.35)] / 0.9
? = 72 × (– 24.7) / 0.9
or, ? = - 1976
2. 76% of 960 - 45% of 148 = ?% of 5525
15
20
24
30
None of these
2). Answer: e)
? / 100 × 5525 = 76 × 960 /100 – 45 × 148 /100
? / 100 × 5525 = 729.6 - 66.6 = 663
? = 663 × 100 / 5525 = 12

26
28
None of these
3). Answer: d)
(4^6)^3.7 ÷ (4^4)^4.3 × (4^3)^5 ÷ (4^2)^-4 = (4)^?
(4)^? = (4)^22.2 ÷ (4)^17.2 × (4)^15 ÷ (4)^-8
(4)^? = (4)^(22.2 -17.2 + 15 + 8) = (4)^28
? = 28

Direction (21 – 25): In the following number series only one number is wrong. Find out the wrong number. 21. 18.3, 20.6 , 16, 22.9 , 13.7, 22.2, 11.4
22.2
18.3
13.7
22.9
20.6
21). Answer: a)
The series is,
18.3 + 2.3 = 20.6
20.6 - 4.6 = 16
16 + 6.9 = 22.9
22.9 - 9.2 = 13.7
13.7 +11.5 = 25.2 ≠ 22.2
25.2 - 13.8 = 11.4

22. 9 , 5 , 6 , 10.5 , 23 , 61, 183
183
10.5
61
5
9
22). Answer: c)
The sequence in the series is,
9 x 0.5 + 0.5 = 5
5 x 1 + 1 = 6
6 x 1.5 + 1.5 = 10.5
10.5 x 2 + 2 = 23
23 x 2.5 + 2.5 = 60 ≠ 61
60 x 3 + 3 = 183

125
188
132
126
154
23). Answer: e)
The series is,
188 - 32 = 156 ≠ 154
156 - 16 = 140
140 - 8 = 132
132 - 4 = 128
128 - 2 = 126
126 - 1 = 125

24). Answer: d)
The sequence in the series is,
2 x 1 + 2 = 4
4 x 2 + 3 = 11
11 x 3 + 4 = 37
37 x 4 + 5 = 153 ≠ 151
153 x 5 + 6 = 771

Direction (26-30): In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and given answer:
a) if x > y
b) if x < y
c) if x ≥ y
d) if x ≤ y
e) if x =y, or no relation can be established between x and y.
26. I. 5x^2 – 87x + 378 = 0
II. 3y^2 – 49y + 200 = 0

a)
b)
c)
d)
e)
26). Answer: a)
I. 5x^2 - 45x - 42x + 378 = 0
or,5x(x - 9) - 42(x- 9) = 0
or. (5x - 42)(x -9) = 0
x = 9, 42/5
II. 3y^2 - 24y - 25y + 200=0
or, 3y(y - 8) -25(y - 8) = 0 or, (y - 8)(3y-25)=0
y = 8, 25/3
Hence, x>y

27.I. 10x^2 – x – 24 = 0
II. y^2 – 2y = 0

a)
b)
c)
d)
e)
27). Answer: e)
I. 10x^2 -16x + 15x – 24 = 0
or, 2x(5x -8) + 3(5x - 8)=0
or,(2x + 3)(5x -8) = 0
x = -3/2, 8/5
II. y^2 – 2y = 0
or, y(y -2) = 0
y = 0, 2
i.e. no relationship between x and y.
28. I. x^2 – 5x + 6 = 0
II. 2y^2 – 15y + 27 = 0

a)
b)
c)
d)
e)
28). Answer: d)
I. x^2 - 2x - 3x + 6 =0
or, x(x -2) - 3(x -2) = 0
or, (x -2) (x -3) = 0
x =2, 3
II. 2y^2 - 6y - 9y + 27 = 0
or, 2y(y - 3)-9(y -3) = 0
or, (y- 3) (2y -9) = 0
y = 3, 9/2
hence, x ≤ y
29. I. 3x + 2y = 301
II. 7x – 5y = 74

a)
b)
c)
d)
e)
29). Answer: b)
I. eqn (I) × 5 + eqn (II) × 2
[15x + 10y = 1505] + [14x – 10y = 148] = 29x = 1653
x = (1653/29) = 57
and y = 65
hence, x< y
30. I. 14x^2 – 37x + 24 = 0
II. 28y^2 – 53y + 24 = 0

a)
b)
c)
d)
e)
30). Answer: c)
14x^2 - 37x + 24 = 0
or, 14x^2 - 21x- 16x + 24 = 0
or, 7x(2x -3) -8(2x -3) = 0
or, (2x - 3)(7x - 8) = 0
x = (3/2), (8/7)
II. 28y^2 - 53y + 24 = 0
or, 28y^2 -21y - 32y + 24 =0
or, 7y(4y - 3) -8(4y - 3) = 0
or, (7y - 8) (4y - 3) = 0
y = 8/7, 3/4
x ≥ y
