II) y² – 11y = 42

2)

I) 6x + 7y = 4

3)

I) 6x² + 33x + 52 = 4x² + 16x + 19

Answers :

Direction (1-5) :

1) Answer: e)

I) x(x – 5) + 6 = 0

X² – 5x + 6 = 0

(x – 3) (x – 2) = 0

X = 3, 2

II) y² – 11y = 42

(y – 14) (y + 3) = 0

Y = 14, -3

Can’t be determined

2) Answer: a)

6x + 7y = 4 –> (1)

4x – 5y = 22 –> (2)

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

X = 3, y = -2

X > y

3) Answer: c)

I) x = ∜6561

X= √(√6561)

X=√81

X = 9

II) 2x – y = 7

2*9 – y = 7

18 – 7 = y

Y = 11

X < y

4) Answer: e)

I) 3x² – 5x + 2 = 0

3x² – 3x – 2x + 2 = 0

3x(x – 1) – 2(x – 1) = 0

(3x – 2) (x – 1) = 0

X = 2/3, 1 = 1, 0.67

II) 4y²– 7y + 3 = 0

4y² – 4y – 3y + 3 = 0

4y (y – 1) – 3(y – 1) = 0

(4y – 3) (y – 1) = 0

Y = 3/4, 1 = 1, 0.75

Can’t be determined

Direction (6-10) :

6) Answer: c)

The total number of employees working in all the given companies in the year 2012

= > 1200 + 1450 + 1050 + 950 + 1100 + 1250 = 7000

The total number of employees working in all the given companies in the year 2016

= > 1500 + 1650 + 1200 + 1550 + 1450 + 1750 = 9100

Required difference = 9100 – 7000 = 2100

7) Answer: a)

The total number of employees of company P in all the given years together

= > 1200 + 1350 + 1100 + 1150 + 1500 = 6300

The total number of employees of company R in all the given years together

= > 1050 + 1100 + 1200 + 1400 + 1200 = 5950

Required ratio = 6300: 5950 = 126: 119

8) Answer: b)

Total number of employees in company Q and S together in the year 2012

= > 1450 + 950 = 2400

Total number of employees in company R and U together in the year 2015

= > 1400 + 1500 = 2900

Required % = (2400/2900)*100 = 83 %

9) Answer: d)

The total number of employees in the year 2014 in all the given companies together

= > 1100 + 1250 + 1200 + 1300 + 1050 + 1600 = 7500

Required average = 7500/6 = 1250

10) Answer: a)

Total number of employees of company Q in all the given years together

= > 1450 + 1300 + 1250 + 1500 + 1650 = 7150

Total number of employees of company U in all the given years together

= > 1250 + 1300 + 1600 + 1500 + 1750 = 7400

Required % = [(7400 – 7150)/7400]*100 = 3 % less
