b) If x ≥ y

c) If x < y

d) If x ≤ y

e) If x = y or no relation can be established between x and y

 

6) I) 5x2 – 3x – 26 = 0

II) 4y2 – 8y – 32 = 0

 

7) I) 3x2 – 5x – 22 = 0

II) 2y2 + 4y – 16 = 0

 

8) I) 4x + 5y = 2

II) 5x – 2y = 19

 

9) I) 3x2 – 26x + 48 = 0

II) y2 – 15y – 34 = 0

 

10) I) x2 – 13x + 42 = 0

II) y2 – 15y + 56 = 0

Answers :

Direction (1-5) :

1) Answer: c)

The total number of laptops in lab A and C together

= > 22 + 20 = 42

The total number of desktops in lab B and D together

= > 28 + 37 = 65

Required difference = 65 – 42 = 23

2) Answer: a)

The total number of desktops in lab E and F together

= > 40 + 35 = 75

The total number of laptops in lab D and E together

= > 14 + 12 = 26

Required ratio = 75: 26

3) Answer: d)

Total number of desktops in lab B, C and D together

= > 28 + 30 + 37 = 95

Total number of laptops in lab A, E and F together

= > 22 + 12 + 26 = 60

Required % = (95/60)*100 = 158 %

4) Answer: b)

The total number of laptops in all the given labs together

= > 22 + 16 + 20 + 14 + 12 + 26 = 110

5) Answer: c)

The total number of desktops in all the given labs together

= > 34 + 28 + 30 + 37 + 40 + 35 = 204

Required average = 204/6 = 34

Direction (6-10) :

6) Answer: e)

I) 5x2 – 3x – 26 = 0

5x2 + 10x – 13x – 26 = 0

5x (x + 2) – 13 (x + 2) = 0

(5x – 13) (x + 2) = 0

X = 13/5, -2 = 2.6, -2

II) 4y2 – 8y – 32 = 0

4y2 – 16y + 8y – 32 = 0

4y (y – 4) + 8 (y – 4) = 0

(4y + 8) (y – 4) = 0

Y = -8/4, 4 = -2, 4

Can’t be determined

7) Answer: e)

I) 3x2 – 5x – 22 = 0

3x2 + 6x – 11x – 22 = 0

3x (x + 2) – 11(x + 2) = 0

(3x – 11) (x + 2) = 0

X = 11/3, -2 = 3.66, -2

II) 2y2 + 4y – 16 = 0

2y2 + 8y – 4y – 16 = 0

2y (y + 4) – 4 (y + 4) = 0

(2y – 4) (y + 4) = 0

Y = 4/2, -4 = 2, -4

Can’t be determined

8) Answer: a)

4x + 5y = 2 –> (1)

5x – 2y = 19 –> (2)

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

X = 3, y = -2

X > y

9) Answer: e)

I) 3x2 – 26x + 48 = 0

3x2 – 18x – 8x + 48 = 0

3x(x – 6) – 8 (x – 6) = 0

(3x – 8) (x – 6) = 0

X = 8/3, 6 = 2.66, 6

II) y2 – 15y – 34 = 0

(y – 17) (y + 2) = 0

Y = 17, -2

Can’t be determined

10) Answer: d)

I) x2 – 13x + 42 = 0

(x – 6) (x – 7) = 0

X = 6, 7

II) y2 – 15y + 56 = 0

(y – 8) (y – 7) = 0

Y = 8, 7

X ≤ y
