Answers:

1). Answer: d

1890/x = ((15 * 20) + 21 – (12/2))/7

1890/x = (300 + 21 – 6)/7

1890/x = 315/7

x = 1890/45

x = 42

2). Answer: a

(450x/100) – 192 ÷ 12 = 2 + 4 – 4

(9x/2) – 16 = 2

9x/2 = 18

X = 4

3). Answer: e

x + 45 = (12/7) * 56 + (11/400)*1200 – 18 * (26/13) + √144

x + 45 = 96 + 33 – 36 + 12

x = 105 – 45

x = 60

4). Answer: c

26 % of 350 + x = √676 + 622 – 15 ÷ 3 × 2

(26/100)*350 + x = 26 + 3844 – 10

91 + x = 3860

x = 3860 – 91

x = 3769 = 3770

5). Answer: b

x * √[109 + √(138 + 6)] = 1268 – (33/11)*(12/100)*550

x * √[109 + √144] = 1268 – 198

x * √[109 + 12] = 1070

x * 11 = 1070

? = 1070 / 11 = 97 = 100

Direction (6-10)

6). Answer: e

3x – 2y = -5 —> (1)

5x – 7y = 10 —> (2)

By solving the equation (1) and (2), we get,

X = -5, y = -5

X = y

7). Answer: d

I. 3x2 + 4x – 64 = 0

3x2 – 12x + 16x – 64 = 0

3x(x – 4) + 16(x – 4) = 0

(3x + 16) (x – 4) = 0

X = -16/3, 4 = -5.33, 4

II. 2y2 – 21y + 52 = 0

2y2 – 8y – 13y + 52 = 0

2y(y – 4) – 13(y – 4) = 0

(2y – 13) (y – 4) = 0

Y = 13/2, 4 = 6.5, 4

X≤ y

8). Answer: e

I. x2 – 6√3 + 24 = 0

(x – 4√3) (x – 2√3) = 0

X = 4√3, 2√3

II. y2 – 7√3 + 36 = 0

(y – 4√3) (y – 3√3) = 0

Y = 4√3, 3√3

Can’t be determined

9). Answer: e

I. x4 = 625

X2 = 25

X = ±5

II. y5 = 243

Y5 = (3)5

Y = 3

Can’t be determined

10). Answer: e

I. 7x2 – 67x + 126 = 0

7x2 – 49x – 18x + 126 = 0

7x(x – 7) – 18(x – 7) = 0

(7x – 18) (x – 7) = 0

X = 18/7, 7 = 2.55, 7

II. 8y2 – 78y + 162 = 0

8y2 – 24y – 54y + 162 = 0

8y(y – 3) – 54 (y – 3) = 0

(8y – 54) (y – 3) = 0

Y = 54/8, 3 = 3.675, 8

Can’t be determined

11). Answer: b

The age of 5 members 3 years ago = 5 * 18 = 90 years

Total age of 5 members at present = 90 + (5×3) = 105 years

Total age of 6 members at present = 6 × 18 = 108 years

The age of baby = 108 – 105 = 3 years

12). Answer: d

Let the cost price be Rs. 1

Selling price of mixture = Rs. 1

Cost price of mixture = 1*100/130 = 10/13

= > – (10/13) : – (3/13)

= > 10: 3

13). Answer: a

Let Pipe P should be closed after ‘x’ min,

(x/16) + (15/24) = 1

(x/16) = 1 – (5/8)

(x/16) = (3/8)

X = 6 min

After 6 min, Pipe P is closed.

14). Answer c

Loss = C.P – 7800

Profit = 9500 – CP

Profit = (70/100)*Loss

9500 – C.P = (7/10) [C.P – 7800]

95000 – 10 C.P = 7 C.P – 54600

17 C.P = 149600

C.P = 8800

Selling price = 8800*(125/100) = Rs. 11000

15). Answer: b

Let B does the work in x days,

A does one-fourth work in 3x/4 days

A does whole work in 3x days

According to the question,

(A + B)’s one day work = > (1/3x) + (1/x) = (1/15)

= > (1 + 3)/3x = (1/15)

= > 4/3x = (1/15)

= > x = 20 days

Direction (16-20)

16). Answer: c

The Sales turnover of company A

=>24000* (100+20)/100 = 24000* 120/100 = 28800

The Sales turnover of company B

=>35000*(100+30)/100 = 35000*130/100 = 45500

The Sales turnover of company D

=>34000* (100+15)/100 = 34000*115/100 = 39100

Required average = (28800+45500+39100)/3

= > 37800

17). Answer: a

The Sales turnover of company B

=>35000*(100+30)/100 = 35000*130/100 = 45500

The profit earned by Company B

= > Sales turnover of company B – Expenses of company B

= > 45500 – 35000

= > 10500

The profit earned by Company C

= > Sales turnover of company C – Expenses of company C

= > [27000*(110/100)] – 27000

= > 29700 – 27000 = 2700

Required difference = 10500 – 2700 = 7800

18). Answer: d

Total sales turnover of Company B and E together

= > 35000*130/100 + 42000*(125/100)

= > 45500 + 52500

= > 98000

Total sales turnover of Company C and D together

= > 27000* 110/100 + 34000*115/100

= > 29700 + 39100

=>68800

Required % = (98000/68800)*100 = 142 %

19). Answer: b

The total expenses of company A and E together

= > 24000 + 42000 = 66000

The total expenses of company B and D together

= > 35000 + 34000 = 69000

Required ratio = 66000: 69000 = 22: 23

20). Answer: e

Total profit earned by company A and C together

= > (24000*20/100) + (27000*10/100)

= > 4800 + 2700

= > 7500

Total profit earned by company B and E together

= > (35000*30/100) + (42000*25/100)

= > 10500 + 10500

= > 21000

Required % = [(21000 – 7500)/21000]*100 = 64 %
