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 value should come in place of question mark (?) in the following questions?
1). 4(2/3)+6(7/5)-11(5/3)+3(4/7) = ?

1). Answer: b)
(14/3)+(37/5)-(38/3)+(25/7) = (490+777-1330+375)/105
= 312/105 = 2(102/105)

2). (4/7)×2126÷11.4+26% of 520

2). Answer: b)
? = 0.57×2126÷11.4+26% of 520
? = 0.57×2126÷11.4+135.2
= 0.57×186.5+135.2
= 106.3+135.2 = 241.5

3). 15.006×?×25.985 = 56745

3). Answer: b)
15.006×?×25.985 = 56745
389.93×? = 56745
? = 56745/389.93
? = 145.53

4). (50)3 ÷ (25)2 + 2466 = ?

4). Answer: a)
(50×50×50)/(25×25) = 200
200+2466 = 2666

5). [(5.6/7.8 ×9.8/2.88) ÷ (34.2/6 × 20/4.5) ] % of 2345 = ?

5). Answer: e)
? = (5.6×9.8×6×4.5)/(7.8×2.88×34.2×20)% of 2345
? = (0.09643/100) ×2345 = 2.26

6). 1006.7+12328.98-5644.64 = 12543 - ?

6). Answer: c)
13335.68-5644.64 = 12543 - ?
7691.04 = 12543 - ?
? = 4851.96

7). 45% of 2345 + 56% of 765 – 12% of 789 ×75% of 433 + ? = 0

7). Answer: a)
0 = ? + 1055.25 + 428.4 – 94.68 × 324.75
0 = ? + 1055.25 + 428.4 –30747.33
? = 29263.68

8). (124÷23) + (56×76) – (45÷ 2.4) = ?

8). Answer: d)
? = 5.39 + 4256 – 18.75
? = 4261.39 – 18.75 = 4242.64

9). (7.84)1/2 × (47.61)1/2 – 92161/2 = ?

9). Answer: c)
= 2.8 ×6.9 – 96
= 19.32 – 96
= – 76.68

10). 46% of ? = 46916

10). Answer: b)
(46/100) × ? = 46916
? = (46916×100)/46 = 101991.3

Direction (11-20): What approximate value should come in place of question mark (?) in the following questions?
11). 108 × 107 × 96 = ?

11). Answer: d)

12). Answer: c)
8(2/7) + 30% of 60 + 10(5/9) = ?
? = 58/7 + 18 + 95/9
? ≈ 8 + 18 + 11 = 37

13). 8.94% of 540 – 9.2% of 324 = ?

13). Answer: c)
8.94% of 540 – 9.2% of 324 = ?
? ≈ 8.9 × 5.4 – 9 × 3.2 = 19.26
Nearest value in options is 19

14). 23(2/15) x 16 (8/9) +8(1/3) = ?

14). Answer: a)
? = 23(2/15) x 16 (8/9) +8(1/3)
? = 347/15 × 152/9 + 25/3
? ≈ 391 + 8 = 399

15). √224 x 12.05 + ³√342 x 4 = ?

15). Answer: c)
? = √224 x 12.05 + ³√342 x 4
? ≈ 15 * 12 + 7 * 4
? = 180 + 28 = 208

16).√(1230) + √(4230) = ?

16). Answer: c)
√(1230) + √(4230) ≈ √(1225) + √(4225) = 35 + 65 = 100

17). 7 (3/11) × 626 – 7(1/3) = ?

17). Answer: b)
7(3/11) × 626 – 7(1/3)
[(80 ×626) / 11] – 7(1/3) = 4552 – 7 = 4545

18). 49% of 5051 – (3/7) of 999 = ?

18). Answer: b)
[(49 × 5051) / 100] – (3/7) × 999 = 2475 – 430 = 2045

19). 4329 / 19 + 6464 / 13 = ?

19). Answer: a)
(4329 / 19) + (6464 / 13) = 228 + 497 = 725

22). 25, 89, 332, 588, 713, ?

22). Answer: c)
The series is 25 + 2^6, 89 + 3^5, 332 + 4^4, 588 + 5^3, 713 + 6^2

23). 18, 36, 62, 96, 138, ?

23). Answer: e)
The difference of difference of the series is 8.
18 + 18 = 36
36 + (18+8) = 36 + 26 = 62
62 + (26+8) = 62 + 34 = 96
96 + (34+8) = 96 + 42 = 138
138 + (42+8) = 188

24). 16, 24, 60, 210, 945, ?

24). Answer: a)
The series is 16×1.5, 24×2.5, 60×3.5, 210×4.5, 945×5.5

25).8, 18, 86, 308, 828, ?

25). Answer: d)
The series is,
8 + (2^3 + 2) = 18,
18 + (4^3 + 4) = 86,
86 + (6^3 + 6) = 308,

26). I. 3x^2 – 4x – 15 = 0,
II. 3y^2 + 11y + 10 = 0

26). Answer: c)
3x^2 – 4x – 15 = 0

3x^2 – 9x + 5x – 15 = 0
Gives x = -5/3, 3
3y^2 + 11y + 10 = 0
3y^2 + 6y + 5y + 10 = 0

Gives y = -2, -5/3
Hence, x ≥ y

27). I. 3x^2 + 17x + 24 = 0,
II. 3y^2 – 4y – 32 =

27). Answer: d)
3x^2 + 17x + 24 = 0
Gives x = -3, -8/3
3y^2 – 4y – 32 = 0
3y^2 – 12y + 8y – 32 = 0
Gives y = -8/3, 4
Hence, x ≤ y

28). I. 3x^2 – 2x – 16 = 0,
II. 3y^2 – 20y + 32 = 0

28). Answer: d)
3x^2 – 2x – 16 = 0
Gives x = -2, 8/3
3y^2 – 20y + 32 = 0
3y^2 – 20y + 32 = 0
Gives y = 8/3, 4
Therefore x ≤ y

29). I. 2x^2 + 5x – 12 = 0,
II. 4y^2 – 19y – 30 = 0

29). Answer: e)

2x2 + 5x – 12 = 0
2x^2 + 8x – 3x – 12 = 0
Gives x = -4, 3/2
4y^2 – 19y – 30 = 0
4y^2 – 24y + 5y – 30 = 0
Gives y= -5/4, 6
Therefore, the relation cannot be establishe

30). I. 2x^2 – 17x + 36 = 0,
II. 3y^2 – 2y – 8 = 0

30). Answer: a)
2x^2 – 17x + 36 = 0
2x^2 – 8x – 9x + 36 = 0
Gives x = 4, 9/2
3y^2 – 2y – 8 = 0
3y^2 – 6y + 4y – 8 = 0
Gives y= -4/3, 2
Therefore, x > y
