Answers: 

Directions(1-5):

1)Answer: c

√?=38.5-(34+16)=-11.5

∴?=-11.5 * -11.5 =132.25

 

2). Answer: a

?={ (63.75×5600)/100 }+{ (42×32500)/100 }

=3570+1365 =4935

 

3). Answer: b

?=1311÷1.9+8525÷625

=690+13.64 =703.64

 

4). Answer: b

34). (?×1800)/100 =(39)^2-(24)^2

=(39+24)(39-24)=63×15

∴?=(63×15)/18

? =52.5%

 

5). Answer: e

7×(3/7)%of 4921+8×(1/3)% of 2463=? – 191.81 0r

(52/7)× (4921/100)+ (25/300) ×2483 =?+191.81

∴ ? = 365.56+205.25 -191.81 =379

 

Direction (Q. 6-10):

6). Answer: b

4, 12, 42, 196, 1005, 6066, 42511

4× 2+(2)^2= 12

12× 3+(3)^2= 45

45× 4+(4)^2= 196

196× 5+(5)^2= 1005

1005× 6+(6)^2= 6066

6066× 7+(7)^2= 42511

Hence, 42 is the wrong number

 

7). Answer: d

7, 13, 25, 49, 97, 194, 385

7 × 2 -1= 13

13× 2 -1= 25

25× 2 -1= 49

49× 2 -1= 97

97× 2 -1= 193

193× 2 -1= 385

Hence, 194 is the wrong number

 

8). Answer: c

10, 15, 24, 35, 54, 75, 100

10+5 =15

15+9 = 24

24+13 =37

37 + 17 =54

54 + 21 =75

75+25 =100

Hence, 35 is the wrong number

 

9). Answer: d

2, 8, 32, 148, 765, 4626, 32431

2 × 2+2^2= 8

3 × 8+3^2= 33

4 × 33+4^2= 148

5 × 148+5^2= 765

6 ×765+6^2= 4626

7 × 4626+7^2=32431

Hence, 32 is the wrong number.

 

10). Answer: d

73, 57, 49, 44, 43, 42

73-57= 16

57-49=8

49-45= 4

45-43= 2

43-42=1

 

Direction (Q. 11-15):

  1. Answer: a

Speed of Sebastian Vettel on Canada

= 302/8

= 37.75 kmph

 

  1. Answer: a

Total distance travelled by all the Players on Austria, Spain and China together

Austria = (292 + 284 + 260 + 274 + 290 + 242) km = 1642 km

Spain = (288 + 300 + 310 + 278 + 260 + 275) km = 1711 km

China = (320 + 264 + 308 + 314 + 318 + 314) km = 1838 km

Total = 1642 + 1711 + 1838

= 5191 km

 

  1. Answer: a

Required average distance covered by Nico Rosberg

= (325 + 314 + 312 + 278 + 292 + 274)/6

= 1795/6

= 299 1/6 km

 

  1. Answer: a

Required time

= 240/19.2

= 12.5 hours

= 12 hours 30 minutes

= 292/21.9

= 13.33 hours

= 13 hours 20 minutes

Difference = 13 hours 20 minutes – 12 hours 30 minutes

= 50 minutes

 

  1. Answer: c

Time taken by Fernando Alonso on China and Austria

= 308 + 260 = 568

Time taken by Daniel Ricciardo on China and Austria

= 318 + 290 = 608

Required ratio =568:608

= 71 : 76

 

  1. Answer: a

Scheme A      Scheme B

Invested x      7200 – x

Let Rs. x be invested for 6, years at the rate 12% per annum.

And Rs. (7200 – x) be invested for 2 years at the rate of 12% per annum.

Now, 6 x 12% of x + 2 x 12% of (7200 – x) = 4008

24/100(3x+7200-x)=4008

2x+7200=16700

2x=9500

X=4750

 

  1. Answer: d

Area of the circular plot = πr2

= (22/7) × 21× 21

Area of the remaining part of the circular

plot = [ (22/7) × 21× 21] – (231 / 6 )

= 66 x 21 – 38.5 = 1386 — 38.5 = 1347.5 sq metre..

 

  1. Answer: d

Length of train = 54 x 14 x (5 / 18) = 210 metres

Time taken by the man to cross the stationary train = (210×18) / (7 x 5) = 6 x 18 = 108 seconds

 

  1. Answer: e

Ratio of profit A ; B : C

So,      A :                               B:                    C

18600×1.5x               15000xx                     12000×2x

Or, 27x                       15x                              24x

9x                                5x                                8x

Now, 5x = 2725

8x = (2725 / 5) x 8 = Rs. 4360

C’s share in profit = Rs. 4360

 

  1. Answer: d

Ratio of capital of Anita, Sunita and Manita is (50000 x 3 + 70000 x 9) : (40000 x 1+ 30000 x 11) : (70000- x 11) = 78 : 37 : 77

Share of Manita in profit

= [77 / (78+37+77)] x18240 = (77 /192 )x18240  = 7315
