b) If x ≥ y

c) If x < y

d) If x ≤ y

e) If x = y or the relation cannot be established

1) I) 7x – 5y = 4x – 3y

II) 8x – 7y + 1 = 3x – 4y

2) I) x2 + 24x + 128 = 0

II) y2 + 23y + 132 = 0

3) I) x2 + 14x + 48 = 0

II) y2 – 6y – 55 = 0

4) I) 3x2 + 14x + 15 = 0

II) 3y2 – 13y + 14 = 0

5) I) x2 – x – 132 = 0

II) y2 – 11y + 30 = 0

Answers :

1) Answer: a)

I) 7x – 5y = 4x – 3y

7x – 4x – 5y + 3y = 0

3x – 2y = 0 –à (1)

II) 8x – 7y + 1 = 3x – 4y

8x – 3x – 7y + 4y = -1

5x – 3y = -1 –à (2)

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

x = – 2, y = -3

X > y

2) Answer: e)

I) x2 + 24x + 128 = 0

(x + 16) (x + 8) = 0

X = -16, -8

II) y2 + 23y + 132 = 0

(y + 12) (y + 11) = 0

Y = -12, -11

Can’t be determined

3) Answer: c)

I) x2 + 14x + 48 = 0

(x + 6) (x + 8) = 0

X = -6, -8

II) y2 – 6y – 55 = 0

(y – 11) (y + 5) = 0

Y = 11, -5

x < y

4) Answer: c)

I) 3x2 + 14x +15 = 0

3x2 + 9x + 5x + 15 = 0

3x (x + 3) + 5 (x + 3) = 0

(3x + 5) (x + 3) = 0

x= -5/3, -3

II) 3y2 – 13y + 14 = 0

3y2 – 6y – 7y +14 = 0

3y (y – 2) -7 (y – 2) = 0

(3y – 7) (y – 2) = 0

y= 7/3, 2

x < y

5) Answer: e)

I) x2 – x – 132 = 0

(x – 12) (x + 11) = 0

X = 12, -11

II) y2 – 11y + 30 = 0

(y – 5) (y – 6) = 0

Y = 5, 6

Can’t be determined

6) Answer: b)

The total number of projects done by company P in all the given years together

= > 75 + 80 + 95 + 60 + 90 = 400

The total number of projects done by company R in all the given years together

= > 90 + 105 + 95 + 100 + 85 = 475

Required difference = 475 – 400 = 75

7) Answer: d)

The total number of projects done by all the given companies in the year 2013

= > 75 + 60 + 90 + 55 + 40 = 320

The total number of projects done by all the given companies in the year 2015

= > 95 + 85 + 95 + 65 + 75 = 415

Required ratio = 320 : 415 = 64 : 83

8) Answer: a)

Total number of projects done by company Q in all the given years together

= > 60 + 70 + 85 + 75 + 80 = 370

Total number of projects done by company S in all the given years together

= > 55 + 70 + 65 + 75 + 90 = 355

Required % = (370/355)*100 = 104 %

9) Answer: c)

The average number of projects done by all the given companies together in the year 2014

= > (80 + 70 + 105 + 70 + 60)/5

= > 385/5 = 77

10) Answer: b)

Total number of projects done by company T in all the given years together

= > 40 + 60 + 75 + 80 + 95 = 350

Total number of projects done by all the given companies in the year 2017

= > 90 + 80 + 85 + 90 + 95 = 440

Required % = [(440 – 350)/440]*100 = 20.45 % = 20 % less
