1. Answer: b)

Explanation:

2. Answer: a)

Explanation:

3. Answer: d)

Explanation: 2524.79 × 29.92 + 495.26 = 76037 or 76000 approx

4. Answer: c)

Explanation: (8736 - 4454 - 2613) + 1311 = ?

1669 + 1311 = 2980

5. Answer: d)

Explanation: (42.13)^{2} + (23.96) ^{2} - (17.11)^{2}

1775 + 574 – 293 = 2056

6. Answer: c)

Explanation: 110 111 103 130 66 ?

+1^{3} –2^{3} +3^{3} –4^{3} +5^{3}

Hence, question mark (?) will be replaced by 191.

7. Answer: a)

Explanation: **64** 128** 92** 156 **148** 212 ?

See the bold part. It makes a series as follows:

64 92 148 ?

+28 +56 +112

Hence, ? will be replaced by 260.

8. Answer: b)

Explanation: Here the series consists of two series S_{1} and S_{2}:

S_{2}: 14 15 16

+1 +1

The next term will be 17.

9. Answer: e)

Explanation: Here the series is:

5 × 1 + 1^{2} = 6;

6 × 2 + 2^{2} = 16;

16 × 3 + 3^{2} = 57;

57 × 4 + 4^{2} = 244;

244 × 5 + 5^{2} = 1245;

1245 × 6 + 6^{2} = 7506

10. Answer: b)

Explanation: Here the series is: 3 × 8 – 7 = 17

17 × 7 – 6 = 113**113 × 6 – 5 = 673**

673 × 5 – 4 = 3361

3361 × 4 – 3 = 13441

13441 × 3 – 2 = 40321

11. Answer: d)

Explanation: Let √x = a

56a^{2} - 99a + 35 = 0

56a^{2} - 49a - 40a + 35 = 0

7a(8a - 7) - 5(8a - 7) = 0

a = 7/8, 5/7

x = 49/64, 25/49

Let √y = b

32b^{2} - 52b + 21 = 0

32b^{2 }- 28b - 24b + 21 = 0

4b(8b - 7) - 3(8b - 7) = 0

b = 3/4, 7/8

y = 9/16, 49/64

Hence, x≤y

12. Answer: a)

Explanation: x^{2} - 5√3x + 35√21 - 7√7x = 0

x(x - 5√3) - 7√7(x - 5√3) = 0

x=7√7, 5√3

y^{2} - 5√5y + 30 = 0

y^{2} - 2√5y - 3√5y + 30 = 0

y(y - 2√5) - 3√5(y - 2√5) = 0

y = 3√5, 2√5

Hence, x > y

13. Answer: c)

Explanation: 16x^{2} + 14x - 15 = 0

16x^{2 }+ 24x - 10x - 15 = 0

8x(2x + 3) - 5(2x + 3) = 0

x = 5/8, - 3/2

20y^{2} - 31y + 12 = 0

20y^{2} - 15y - 16y + 12 = 0

5y(4y - 3) - 4(4y - 3) = 0

y = 4/5, 3/4

Hence, x < y

14. Answer: a)

Explanation: 6x + 5y = 61 …….(i)

5x - 6y = 60 …….(ii)

Multiplying equation (i) and (ii) with 5 and 6 respectively, we get

30x + 25y = 305

30x - 36y = 360

Solving both the equations, we get

y = - 55/61, x = 666/61

Hence, x > y

15. Answer: c)

Explanation:

16. Answer: (b)

Explanation:

Percentage of liquid B initially present in the jar= 2×100/5= 40 %

Percentage of liquid B finally present in the jar= 4×100/5=80%

let us liquid B initially present in the jar as the first solution in which the percentage of liquid B is 40% The second solution is liquid B which is being mixed and it has 100 % liquid B.

So, 80 % of the liquid B present in the resultant mixture may be taken as average percentage.

Using rule of allegation on liquid B present we can write

Or, the ratio of liquid left in the jar to liquid B being mixed =1:2

Since the quantity if liquid B being mixed is 20 litres. The quantity of liquid left in the jar is 10 litres.

Therefore, the total quantity of liquid initially present in the vessel=10+20=30 litres quantity of liquid A=3/(2+3)=18 litres.

17. Answer: a)

Explanation: Let CP = 100

So, MP = 150

SP = 120

Discount = 150 – 20 = 30

Discount % = 20%

18. Answer: b)

Explanation: Let the students passed be 7x and failed be 4x.

(7x + 8) / (4x - 8) = 9/2

X = 4

Number of students failed = 4x = 4 × 4 = 16

19. Answer: c)

Explanation: Let the speed of the train be x km/hr and that of the car be y km/hr.

Then, 240/x + 960/y = 16 .... (i)

And, 400/x + 800/y = 50/3 .... (ii)

Solving (i) and (ii), we get: x = 60 and y = 80.

Ratio of speeds = 3 : 4.

20. Answer: b)

Explanation: Speed of the train = (72 × 5/18) m/sec = 20 m/sec

Distance moved in passing the pole = 180m

Required time taken = (180/20) sec = 9 sec

21. Answer: c)

Explanation: In 20 hours, one project is completed by X and in the same time, Y + Z will complete 2.5 project and X + Y + Z will complete 3.5 projects in 20 hours.

Thus, to complete 28 projects, 160 hours are needed.

22. Answer: c)

Explanation: Amount = P (1 + r_{1}/100)(1 + r_{2}/100)(1 + r_{3}/100)

= 12,500(1 + 3/100)(1 + 4/100)(1 + 5/100)

= Rs.14,059.50

23. Answer: a)

Explanation:

24. Answer: 2)

Explanation: Ratio of A,B and C.

A: B: C = (50000 × 12 + 70000 × 12 + 70000 × 12) : (70000 × 12 + 90000 × 12) : (70000 × 12)

= 2280000: 1920000: 840000 =19: 16: 7

A’s share = Rs. (2,10,000 × 19/42) = Rs. 95,000

25. Answer: a)

Explanation: Net part filled by both pipes A and B together in 1 hour

=1/20 + 1/30 = (30+20) / 600 = 1/12

Hence the time taken to fill the tank = 12 hours

26. Answer: b)

Explanation: Number of Marketing students in Institute A = 32500

Number of Finance students in Institute D = 37500

The ratio= 32500:37500 =13:15

27. Answer: d)

Explanation: Total number of students in Institute D in all three faculties = 22500 + 35000 + 37500 = 95000

The average student in each faculty = 95000/3 = 31667

28. Answer: b)

Explanation: The number of IT students in all the Institutes = 27500 + 30000 + 22500 + 22500 = 102500

The average IT students in each Institute = 102500/4 = 25625

29. Answer: d)

Explanation: The total number of IT students in Institute C = 22500

Total number of students in Institute C = 80000

Percentage of IT students = 22500/80000 × 100 = 28.13%

30. Answer: e)

Explanation: Total number of Finance students in all the Institutes = 127500

Total number of IT students in all the Institutes = 102500

Their difference = 127500 - 102500 = 25000

31. Answer: d)

Explanation: Percentage of Indian IT Professionals working either in Australia or New Zealand is 14% + 12% = 26%

32. Answer: a)

Explanation: Ratio of Indian IT Professionals working in Middle East to Australia is 28:14 = 2:1

33. Answer: d)

Explanation: Population of Indian IT Professionals in USA and UK is 36%. So rest of the population is 64% that is 19200.

So, Population of Indian IT Professionals in USA and UK is

36 × (19200/64) = 10800

34. Answer: b)

Explanation: Percentage of Indian IT Professionals working in Europe currently is 10%.

If doubled, then the new population of Indian IT Professionals population working abroad will be is 20/110 = 18.18%

35. Answer: c)

Explanation: If tripled the percentages become 78 and 30. The ratio is 78:30 = 13:5
