Answers: 

Directions (Q. 1-5):

1).  Answer a

(12/17) × (25/100) × 1020 = 120 + ?

=> 180 = 120 + ?

=> ? = 180 – 120 = 60

2). Answer b

[(25 × 26)/13] – 9 = ? – 16

=> 41 = ? – 16

=> ? = 41 + 16 = 57

3). Answer b

[(420 × 36) / 100] – [(350 × 56) / 100]

= ? – 94

=> 151.2 – 196 = ? – 94

=> ? = 151.2 + 94 – 196 = 49.2

4). Answer a

? = 540 × (75/100) × (7/5) × (2/3) = 378

5).  Answer c

33 × (9)5 ÷ (33)2= 3?

=> 33 × 32 * 5 ÷  36 = 3?

=> 33+10-6 = 3?

=> 37 = 3?

=> ? = 7

Directions (Q. 6-10):

  1. Answer a

The series is × 2 – 1, × 3 – 1, ×4 – 1, ×5 -1, ×6 – 1.

  1. Answer b

The series is difference of difference +22, +44, +66, +88, +110.

  1. Answer c

The series is ×8, ×7, ×6, ×5, ×4, ×3, ×2

  1. Answer c

The series is +1^3 + 1, +3^3 + 1, +5^3 + 1, +7^3 + 1, +9^3 + 1.

  1. Answer e

The series is -11^2, -9^2, -7^2, -5^2, -3^2.

Direction (Q. 11-15):

  1. Answer e

Total candidates selected:

2015 = 1030

2017 = 1150

Required ratio = 1030 : 1150

= 103 : 115

  1. Answer b

Total candidates selected in 2016

= 10 + 30 + 160 + 360 + 250 + 220 = 1030

Required percentage = 250/1030 × 100

= 24%

  1. Answer d

Total number of candidates selected in Andra Bank

= 80 + 10 + 50 = 140

Required percentage

= 140/1030 × 100

= 14%

  1. Answer a

Total number of candidates selected in 2015

= 80 + 40 + 100 + 330 + 280 + 200 = 1030

Canara Bank + UCO Bank

= (100 + 130 + 160) + (200 + 220 + 260)

= 390 + 680

= 1070

Required ratio = 1030 : 1070

= 103 : 107

  1. Answer c

In 2017

Canara Bank + Indian Bank

= 130 + 290 = 420

UCO Bank + Andra Bank

= 260 + 50 = 310

Required percentage

= 420/310 × 100

= 135%

  1. Answer d

Area of the square = 196 sq cm

Side of the square = 14 cm

:. Radius of the larger circle = 28 cm

Radius of the smaller circle = 28 × (3/7) = 12 cm

Circumference of the smaller circle = 2 ×π× 12 = 24 π cm

  1. Answer a

Sum of angle = (3x + 4x + 6x + 7x) = 3600 or, 20x = 360°

x = 18°

Second largest angle = 6 x 18° = 108°

Smaller angle of parallelogram = 1/2 x108° = 54°

Value of adjacent angle = 180° — 54° = 126°

  1. Answer a

Required value = (27)2 x 5 x 4/9 x 24/100 = 388.8

  1. Answer d

Speed along the stream = 25 kmph

And speed against the stream = 10 kmph

Now, the speed of boat in still water = (25+10)/2

And the speed of stream = (25-10)/2

Required ratio = 35/2 : 15/2= 7 :3

  1. Answer b

Manisha’s share = Rs. 3570

Naina’s share = 3570 x 4/5 = Rs. 2856

Total profit = [(3570+2856) / 85] x100

= (6426/85) x100 = Rs. 7560
