Answers:

Directions (Q. 1 – 5):

1. Answer c

4³ × 16² ÷ √ (4096) = 4^x

(4³ × 16 × 16)/64 = 4^x

4⁴ = 4^x

X= 4

2. Answer a

(18 × 21/x) + 352 = 429

18 × 21/x = 77

X= 18 × 21/77

X = 54/11= 5

3. Answer b

154% of 525 + 13% of 1390 = x

(154 * 525)/100 + (13 * 1390)/100 = x

809 +182 = x

X= 991 ≈ 1000

4. Answer d

X² + (45 * 1696) /100 + 359 = 5321

X² = 5321 -359 – 765

X² = 4197

X ≈ 65

5. Answer c

(8/15) of 5026 + (11/200) of 58344 = x

2680 + 3209 = x

X= 5889

Direction (Q. 6 – 10):

6. Answer b

The pattern is, 2* Prime no’s (Starts with 2)

(ie., 2*2, 3*2, 5*2, 7*2, 11*2, 13*2, 17*2)

The answer is, 22

7. Answer d

The pattern is, *2 + 1³, *3 + 2³, *4 +3³, *5 + 4³, *6 + 5³

The answer is, 5519

8. Answer e

The pattern is, *1 + 2, *2 + 4, *3 + 6, *4 + 8, *5 + 10, *6 +12,..

The answer is, 24072

9. Answer c

The pattern is, *3/2

The answer is, 126

10. Answer a

The pattern is, ÷ 2 × 2

The answer is, 5.5

11. Answer b

The sum of money 2 times itself in 5 years. The same amount and the same rate of interest, the 8 times will be in,

Total amount= 2p

S.I = 2p-p =p

P*5*r/100 = p

R= 20%

P*20*n/100 = 7p

N= 35 years

Shortcut method:

=>(n-1)*t (here n is no of time, t is years)

=>(8-1)*5

=>35 years

12. Answer a

P(E) = n(E)/n(S)

n(S) =  ¹³C₂

n(E) = ⁴C₂ or ⁶C₂

P(E) = ⁴C₂ or ⁶C₂ / ¹³C₂

P(E) = (6+15)/78

P(E) = 7/26

13. Answer d

The cost of fencing the plot @ 25 per meter is Rs. 7200

=>7200/25=Perimeter of Rectangle

=>288=2(7x+5x)

=>12x=144

=>x=12

The length and the breadth of rectangular plot are in the ratio of 8:6

=>Length=7x=84, Breadth=5x=60

Area of the plot= 84*60

=>5040 Sq meter.

14. Answer (e)

Ragu, Vinod and Anu enter into a Partnership with shares in the ratio of (9/2) : (7/5) : (5/3)

=>(135:42:50)/30

=>135:42:50

=>351 : 84 : 100

Vinod’s Share= (84/535)*44940 = 7056

15. Answer a

(x-4)/ 15 + (x-5)/18 + x/20 =1

(12x-48+10x-50+9x)/180 =1

31x-98=180

31x= 278

X=278/31 = 8 30/31 min

Directions (Q. 16 – 20):

16. Answer a

The average number of candidates selected over the given period for various states

For Delhi = 94 + 48 + 82 + 90 + 70/5 = 384/5 = 76.8

For HP = 82 + 65 + 70 + 86 + 75/5 = 378/5 = 75.6

For UP = 78 + 85 + 48 + 70 + 80/ = 361/5 = 72.2

For Punjab = 85 + 70 + 65 + 84 + 60/5 = 364/5 = 72.8

For Haryana = 75 + 75 + 55 + 60 + 75/5 = 340/5 = 68

Clearly the average is maximum for Delhi

17. Answer c

The percentages of candidates selected over the candidates appeared in 1997, for various states are:

For Delhi = (94/8000 × 100)% = 1.175%

For HP = (82/7800 × 100)% = 1.051%

For UP = (78/7500 × 100)% = 1.040%

For Punjab = (85/8200 × 100)% = 1.037%

For Haryana (75/6400 × 100)% = 1.172%

Clearly, the percentage is lowest for Punjab

18. Answer d

Required percentage = [(75 + 75 + 55 + 60 + 75) / (94 + 48 + 82 + 90 + 70) × 100]%

= [340/384 × 100]%

= 88.54% ≈ 88.5%

19. Answer d

Required percentage = [(82 + 70 + 48 + 65 + 55)/(640 + 560 + 400 + 525 + 350)]%

= (320/2475 × 100)%

= 12.93% ≈ 13%

20. Answer c

The total no of candidates appeared from all the states during the year 1998

= > 4800 + 7500 +5600 + 6800 +7100 = 31800

The total no of candidates appeared from all the states during the year 2001

= > 9000 + 7200 + 8500 + 5700 + 4500 = 34900

Respective ratio = 31800 : 34900 = 318 : 349
