Crack IBPS Exam 2017 - Quantitative Aptitude Scoring Part (Day-36):

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).36.02% of 449.98 – 14.95% of 180.07 = x – √280 % of 3699.99

1) Answer: E
36% of 450 = 162
15% of 180 = 27
17 % of 3700 = 629
? = 162 – 27 + 629 = 764

2). 15² – 13² + 9² – 6³ = 9⁴ – x

2) Answer: A
x = 9⁴ – (15² – 13² + 9² – 6³) = 6640

3).√1370 + 1060 ÷ 18.002 × 32.09% of 249.99 = x

3) Answer: B
√1370 = 37
1060 ÷ 18 = 59
32% of 250 = 80
x = 37 + 4720 = 4757

4). 3/7 × 1091 + 405 ÷ 17 – 17.03% of 465 = x

4) Answer: C
3/7 × 1091 = 468
405 ÷ 17 = 24
17% of 465 = 79
x = 468 + 24 – 79 = 413

5).20.95% of 410 – 86.03% of 235 = √x – 3000 ÷ 20.98

5) Answer: D
21% of 410 = 86
86% of 235 = 202
3000 ÷ 21 = 143
So (86 – 202 + 143) = √x
√x = 27
x = 729

6).√(43% of 549 + 28% of 1550) = x

6) Answer: E
43% of 549 = 236
28% of 1550 = 434
S0 √(236+434) = x
So x = √676 = 26. Root does not give negative value.

7). 23% of 165 + 34.09% of 44 – 13% of 600 = x

8) Answer: D
470 ÷ 18 + 17.08 × 35.98 – √6240 =560

8). 470 ÷ 18 + 17.08 × 35.98 – √6240 = x

8). Answer: a)
? = 21*58 = 1218

9). 36.09% of 450 + 23.99% of 150 – 43.94% of 260 = x% of 700

9) Answer: C
36.09% of 450 + 23.99% of 150 – 43.94% of 260 = x% of 700
X = 12

10).18.08% of 549.99 – 44.98% of 202.09 = (x)^(1/4)

10) Answer: B
18.08% of 549.99 – 44.98% of 202.09 = (x)1/4
x = 6561

11). 286.04×11.646+65.37×54.08=?+137.989

11) Answer: C
?+137.989=286.04×11.646+65.37×54.08
286×12 + 65×54
3432+3510 = 6942
Or, ?+138 = 6942
?=6942-138=6804 = 6800

12). 85943 + 71206 + 37517 – 3512 + 119 = ?

12). Answer: a)
? = 85940 + 71200 + 37520 – 3510 + 120 = 191270
? ≈ 191300

13). 20440÷639.890=√(?)

13). Answer: d)
√(?) = 20440÷640 = 31.94 ≈ 32
? = 32×32 = 1024

14). 122.05% of 120+149.99% of 150=?

14). Answer: a)
? = (122×120/100)+(150×150/100)
= (146.4+225)
= 371.4
? ≈ 371

15). (9.899)^3×(2.399)^2×(4.005)^4=?

15). Answer: c)
? = (9.9)^3×(2.4)^2×(4)^4
= (970.299)×(5.76)×256
≈ (970.3)×(5.75)×256 = 1428281.6 ≈ 1428200

Direction (16-20): What value should come in place of question mark (?) in the following questions?
16).1 1/4 + 2 4/5 + 3 5/8 + 2 3/10 = x

16). Answer: c)
1000/ 25 = ? – 235
40 = ? – 235
? = 235+40 = 275

17). 1008 ÷ 16 × 3/7 + 19 × 204 = 13 × 15 + x

17). Answer : b)
?=633.72-569.21÷(11.9% of 80)
= 634-570÷(80×12)/100
= 634-570/9.6 =634 – 59.375 =575 (approx)

18). (0.6)^(5/4) ÷ (0.36)^(3/8) × (0.3)^(13/12) ÷ (0.09)^(7/24) = (0.18)^(1-x)

18). Answer : b)
67.69 -11.78 + 19.63 =?+ 22.41
68 – 12+20 = ? + 22 = 88-12 -22 = 54

19). (0.4)^(17/16) ÷ (0.16)^(3/32) × (0.3)^(5/4) ÷ (0.09)^(3/16) = (0.12)^x

19). Answer : c)
?=(50)^2+(60)^2+(64.5)^2 = 2500+3600+4160.25 ≈ 10260

20).30% of 470 + 24% of 250 – 45% of 260 = √x

20). Answer : a)
√? ≈ √1225 + √2209 – √5329
√? = 35 + 47 - 73 = 9
? = 81

Direction (21 – 25): In the following questions, two equations numbered are given in variables x and y. You have to solve both the equations and find out the relationship between x and y. Then give answer accordingly
A) If x > y
B) If x < y
C) If x ≥ y
D) If x ≤ y
E) If x = y or relation cannot be established
21).I. 3x^2 – 25x + 52 = 0,
II. 3y^2 – 16y + 16 = 0

21). Answer: a)
The series is,
872 – 0^2 = 872
872 + 4^2 = 888
888 – 8^2 = 824
824 + 12^2 = 968
968 – 16^2 = 712

22).I. 3x^2 – 8x – 16 = 0,
II. 2y^2 – 5y – 12 = 0

22). Answer: c)
The series is,
69+(1*3*5) = 84
84+(3*5*7) = 189
189+(5*7*9) = 504
504+(7*9*11) = 1197
1197+(9*11*13) = 2484

23). I. 2x^2 – 9x + 4 = 0,
II. 2y^2 – 17y + 36 = 0

23). Answer: d)
The series is,
156+17*1 = 173
173-21*2 = 131
131 + 25*3 = 206
206-29*4 = 90
90+33*5 = 255

24). I. 2x^2 – 9x + 4 = 0,
II. 2y^2 – 17y + 36 = 0

24). Answer: c)
The series is
980÷5 -5 = 191
191*4+4 = 768
768÷3-3 = 253
253*2+2 = 504
504÷1-1 = 503

25). I. 3x2 + 7x – 6 = 0,
II. 3y2 – 19y + 20 = 0

25). Answer: b)
The series is,
33*0.5÷0.1 = 165
165*1÷0.2 = 825

825*1.5÷0.3 = 4125
4125*2÷0.4 = 20625

Direction (26-30): What will come in place of (?) in following series following a certain pattern?
26). 9, 8, 14, 39, ? , 755

26). Answer: e)
(2x+3)(x+4) = 0
X= -3/2, -4
(5y+2)(y+5) = 0
Y = -5, -2/5
Hence, the relation cannot be established.

27). 25, 32, 21, 34, 17, ?

27). Answer: a)
(5x+2)(5x+3) = 0
X = -2/5, -3/5
(5y+10)(y+2) = 0
Y = -2, -10/5 = -2, -2
Hence, x > y

28). 11, 6, 7, 12, ? , 67.5

28). Answer: c)
(x+1)(3x+4) = 0
x = -1, -4/3
(3y+4)(y+2) =0
y = -4/3, -2
Therefore x ≥ y

29). 4, 7, 35, 83, 146, ?

29). Answer: b)
y = 1705 – 1689 = 16
(x + y)^2 = 900
x + y = 30
x = 30 – 16 = 14
Therefore, x < y

30). 521, 496, 447, ?, 245

30). Answer: d)
8X^2 + 3X – 38= 0
(8x + 19) (x – 2) = 0
x = 2 or -19/8
6Y^2 – 29Y + 34 = 0
(y – 2) (6y – 17) = 0
y = 2 or 17/6
Therefore, x ≤ y
