Answers key with detail explanation

Answers:

1) Answer: A

1 + 4(22) = 5

5 + 16(42) = 21

21 + 36(62) = 57

57 + 64(82) = 121

2) Answer: D

113 + 30 = 143

143 + 25 = 168

168 + 20 = 188

188 + 15 = 203

203 + 10 = 213

3) Answer: C

23 * 2 – 3 = 43

43 * 2 – 5 = 81

81 * 2 – 7 = 155

155 * 2 – 9 = 301

301 * 2 – 11 = 591

4) Answer: A

19 + (1 * 2) = 21

21 + (3 * 4) = 33

33 + (5 * 6) = 63

63 + (7 * 8) = 119

119 + (9 * 10) = 209

5) Answer: D

124 * 0.5 = 62

62 * 1 = 62

62 * 1.5 = 93

93 * 2 = 186

186 * 2.5 = 465

6) Answer: E

From I =>3x2 – 19x + 28 = 0

3x2 – 12x-7x+28=0

3x(x-4)-7(x-4)=0

=> (3x – 7) (x – 4) = 0

=> x = 4, 7/3

From II =>5y2 – 29y + 36 = 0

5y2– 20y-9y+36=0

5y(y-4)-9(y-4)=0

=> (5y – 9) (y – 4) = 0

=> y = 4, 9/5

Hence, relationship between x and y cannot be

determined

7) Answer: A

From I =>x2 + 18x + 45 = 0

x2 + 3x +15x+ 45 = 0

x(x+3)+15(x+3)=0

=> (x + 3) (x + 15) = 0










=> x = -3, -15

From II =>2y2 + 3y + 1 = 0

2y2 + 2y+1y + 1 = 0

2y(y + 1)+1(y + 1) = 0

=> (y + 1) (2y + 1) = 0

=> y = -1, -1/2

Hence, x < y

8) Answer: B

From I =>3x2 – 23x + 14 = 0

3x2 – 21x -2x+ 14 = 0

3x(x-7)-2(x-7)=0

=> (3x – 2) (x – 7) = 0

=> x = 2/3, 7

From II =>3y2 + 18y + 24 = 0

3y2 + 12y +6y+ 24 = 0

3y(y+4)+6(y+4)=0

(3y+6)(y+4)=0

=> y = -2, -4

Hence, x > y

9) Answer: D

From I =>x2 – 5x + 6 = 0

x2 – 2x -3x+ 6 = 0

x(x-2)-3(x-2)=0

=> (x – 2) (x – 3) = 0

=> x = 2, 3

From II =>y2 – 3y + 2 = 0

y2 – 1y-2y + 2 = 0

y(y-1)-2(y-1)=0

=> (y – 1) (y – 2) = 0

=> y = 1, 2

Hence, x ≥ y

10) Answer: C

From I =>13x2 – 32x + 12 = 0

13x2 – 26x -6x+ 12 = 0

13x(x-2)-6(x-2)=0

=>(x – 2) (13x – 6) = 0

=> x = 2, 6/13

From II =>7y2 – 29y + 30 = 0

7y2 – 14y-15y + 30 = 0

7y(y-2)-15(y-2)=0

=> (y – 2) (7y – 15) = 0

=> y = 2, 15/7

Hence, x ≤ y

11) Answer: D

5000 + 18 4/5 % of ? = 8297.52

=> 18 4/5 % of x = 3297.52

94/500 * x = 3297.52

X = (3297.52* 500)/94

X = 17540

12) Answer: B

45 + 8 * 15/(240/6) = ?

=> 45 + (8 * 15)/40 = x

=> x = 48

13) Answer: A

10 2/3 * 7 ¾ * 8 ¼ + 2 ½ =?

=> (32/3 * 31/4 * 33/4) + 5/2

=> 684.5

14) Answer: C

[(8 * 6) + (3 * 15) + 2] / [(15 * 2) – 154/7] =?

=> (48 + 45 + 2)/(30 – 22)

=> 11.875

15) Answer: D

20% of ? + 32% of 510 = 213.2

=> 20x/100 + 32/100 * 510 = 213.2

=> 20x/100 = 213.2 – 163.2

=> x = 250

21) Answer: A

Required average = (12 + 15)/200 * 30000 = 4050

22) Answer: C

Required difference = ((25 + 30) – (18 + 15))/100 *

30000 = 6600

23) Answer: E

Required percentage = (18 + 12)/(25 + 15) * 100 =

75%

24) Answer: E

Required ratio = (15 + 30):(18 + 25)

= 45:43

25) Answer: B

Required percentage = (25 – 15)/25 * 100 = 40%

26) Answer: B

Expenditure of Arun = 6000 – 1200 = 4800

Expenditure of Bala = 7200 - 1600 = 5600

Expenditure of Sharu = 14400 – 3200 = 11200

Expenditure of David = 9600 – 1200 = 8400

Expenditure in Divya= 10400 – 1400 = 9000

Expenditure of Esai = 5600 – 1600 = 4000

Expenditure in Divya= 10400 – 1400 = 9000

Savings of Divya = 1400

Required percentage = 1400/9000 * 100 = 15.55%

27) Answer: A

Required average = (1200 + 1600 + 3200 + 1200 +

1400 + 1600)/6 = 1700

28) Answer: C

Required percentage = 7200/(4000 + 8400) * 100 =

58%

29) Answer: C

Average income = (6000 + 7200 + 14400 + 9600 +

10400 + 5600)/6

= 53200/6

Average expenditure = (4800 + 5600 + 11200 + 8400

+ 9000 + 4000)/6

= 43000/6

Required Difference = 53200/6 – 43000/6 = 1700

30) Answer: E

Expenditure of Kavin = 9/8 * 4000 = 4500

20/100 * 4500 = Savings

Savings of Kavin = 900

Income of Kavin = 4500 + 900 = 5400

31) Answer: C

Let the side of the square and other square be a cm

and b cm.

a2 = 121/100 * b2

=>a/b = 11/10

Required % = (4a – 4b)/4b * 100

((44b/10 – 4b)/4b) * 100










4b(11/10 -1) / 4b * 100

= (11/10 – 1) * 100

= 10%

32) Answer: D

Investment ratio = P: Q = 4: 1

Time ratio = P: Q = 3: 4

Profit ratio = P: Q = (4 * 3): (1 * 4) = 3: 1

Profit = (3 + 1)/3 * 3000 = Rs.4000

33) Answer: C

Required difference = P * (r/100)2

=> P * (r/100)2 = (4/100) * P

r2/10000 = 4/100

=> r = 20%

34) Answer: D

Age of new joined employee = Q

Total age of all employees initially = 40P

New average = 40(P + 1)

40P – 30 + Q = 40(P + 1)

=> Q = 70 years

35) Answer: A

Let the price of a doll in 2017 = 100x

Price in 2018 = 95% of 100x = 95x

Price in 2019 = 110% of 95x = 104.5x

Price in 2020 = 84% of 104.5x = 87.78x

Required % = (100x – 87.78x)/100x * 100 = 12.22%

less

37) Answer: C

Upstream speed = 20/2 = 10kmph

Downstream speed = 32/2 = 16kmph

Speed of stream = (16 – 10)/2 = 3kmph

38) Answer: B

Required ratio = 4:4 = 1:1

39) Answer: A

Present age of Mani = 5x

Present age of Ram = 4x

After 2 years Mani = 5x + 2

After 2 years Sam age = (5x + 2) * 7/8

35x/8 + 14/8 – 2 – 4x = 2

3x = 16 – 14 + 16

x = 6

Present age of Mani = 5 * 6 = 30 years

40) Answer: A

d = s * t

d = s * 80/100 * (t + 30)

s * t = s * 4/5 * (t + 30)

5t = 4t + 120

t = 120 minutes= 2 hours
