Dear Readers, Nowadays most of the aspirants are facing huge trouble to increase the overall marks. To score high you need to practice more and more standard questions daily. “Practice does not make perfect, Only Perfect Practice makes perfect”.

Direction (1-10): What approximate value should come in place of question mark (?) in the following questions?
1). 24.95% of 797.07 ÷ 19.05 = 54.88 – ?

1). Answer: B
25% of 800 ÷ 20 = 25*800/100*20 = 10
? = 55 – 10 = 45

2). 45.05^2 – 19.28^2 + √289 = ?^2

2). Answer: D
?^2 = 45^2-19^2 = 2025 – 361 = 1664
?2 = 1664+17 = 1681=41*41
? = 41

3). 1781.90÷54.20 + 456.13 – 2345.80 *0.98 = ? * 2

3). Answer: A
1782÷54+456-2345*1
= 33+456-2345
? = -1856/2 = -928

4). [√(√65535)+144.06] = ?

4). Answer: C
√65535 ≈ 256
? ≈ √(256+144) = √400 = 20

5).(575.01+7510.98 – 467.12 + 543.23) ÷ (76.16*0.49 + 674.85 – 342.03) = √?

5). Answer: B
8162 ÷ (38+675-342)= 8162 ÷ 371 = 22
√? = 22
? = 22*22 = 484

6). (5616÷156)×23.67 = ? ÷ 16.78

6). Answer: D
36*24 = 864
? = 864*17 = 14688

7). (50624.75)^2/4 ÷ (3375.33)^2/3 = (14.99)^?

7). Answer: B
15^4 = 50625 = (15^4)2/4 = 15^2
15^3 = 3375
(15^3)^2/3 = 15^2
15^2÷15^2 = 15^?
? = 0

8). 5/19 × 1368.17 + 3/42 × 1511.92 = ?

8). Answer: C
? = 5*72 + 3*36 = 360+108 = 468

9). 4993.67 ÷ 24.76 – 432.05 + 200.24 = ?

12). √11449×√6241 – 54^2 = ? + 74^2

12). Answer: B
107*79 – 2916 = ? +5476
5537 = ?+ 5476
? = 61

13). 38.89% of 4532 + 45.3% of 1001 + 88 = ?^2

13). Answer: A
1762.5 + 453.5 = 2216
?2 = 2216 + 88 = 2304
? = 48

14). (4×4)^3 ÷ (512÷8) × (2×8)^2 = 2^?

14). Answer: D
2^? = 4096÷64×256
= 64×256 = 2^6 ×2^8
= 2^14
? = 14

Direction (26-30): In each of these questions, two equations I & 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 cannot be established
26). I.5/x – 4/y = -2
II.2/x + 3/y = 13

26). Answer: A
5u-4v = -2 ------*3
=>15u-12v = -6
2u+3v = 13 ------*4
=> 8u+12v = 52
Solve this eq
23u = 46
U=2, v=3
X=1/2,y=1/3
Hence, x > y

27). I.4X^2 + 4X – 3= 0
II.14Y^2 – 17Y + 5 = 0

27). Answer: D
(2X-1)(2X+3) =0
X=1/2, -3/2
(2Y-1)(7Y-5) =0
Y = 1/2, 5/7
Hence, x ≤ y

28). I.2X^2 – 17X + 36= 0
II.Y^2 = 16

28). Answer: C
(2X-9)(X-4) =0
X=9/2, 4
Y = ±4
Therefore x ≥ y

29). I.6X^2 + 19X + 15= 0
II.3Y^2 + 11Y + 10 = 0

29). Answer: C
(3X+5)(2X+3) = 0
X=-5/3, -3/2
(Y+2)(3Y+5) =0
Y = -2, -5/3
Therefore, x ≥ y

30). I.4X^2 + 19X + 21= 0
II.2Y^2 – 23Y + 63 = 0

30). Answer: B
(4x+7)(x+3) = 0
X =-7/4, -3
(2y+9)(y+7) = 0
Y = 9/2, 7
Therefore, y > x
