2)

I) 3x2 – 447 = 420

II) y – √289 = 0

 

3)

I) 2x2 – 15x + 28 = 0

II) 3y2 – 13y + 14 = 0

 

4)

I) x2 – 18x + 77 = 0

Answers :

Direction (1-5) :

1) Answer: c)

5x – 3y = 0 –> (1)

2x – 5y = – 19 –> (2)

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

X = 3, y = 5

X < y

2) Answer: d)

I) 3x2 – 447 = 420

3x2 = 447 + 420

3x2 = 867

X2 = 289

X = 17, -17

II) y – √289 = 0

Y = √289

Y = 17

X ≤ y

3) Answer: a)

I) 2x2 – 15x + 28 = 0

2x2 – 8x – 7x + 28 = 0

2x (x – 4) – 7 (x – 4) = 0

(2x – 7) (x – 4) = 0

X = 7/2, 4 = 3.5, 4

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 = 2.33, 2

X > y

4) Answer: b)

I) x2 – 18x + 77 = 0

(x – 11) (x – 7) = 0

X = 11, 7

II) y2 – 13y + 42 = 0

(y – 6) (y – 7) = 0

Y = 6, 7

X ≥ y

5) Answer: e)

I) x2 – 9x – 52 = 0

(x – 13) (x + 4) = 0

X = 13, – 4

II) y2 – 7x – 44 = 0

(y – 11) (y + 4) = 0

Y = 11, -4

Can’t be determined

Direction (6-10) :

6) Answer: b)

The total number of temporary employees in Company P

= > 2600*(44/100) = 1144

The total number of permanent employees in company T

= > 3800*(22/100) = 836

Required difference = 1144 – 836 = 308

7) Answer: d)

Ratio between the male to that of female employees in company Q = 5: 3

The total number of male employees in company Q

= > 3200*(5/8) = 2000

The total number of permanent employees in company P

= > 2600*(56/100) = 1456

Required ratio = 2000: 1456 = 125: 91

8) Answer: a)

The average number of employees in all the given companies together

= > (2600 + 3200 + 3500 + 2400 + 3800)/5

= > 15500/5 = 3100

9) Answer: c)

Total number of permanent employees in company Q

= > 3200*(64/100) = 2048

Total number of employees in company R = 3500

Required % = (2048/3500)*100 = 58.514 % = 59 %

10) Answer: b)

Total number of employees in company P and Q together

= > 2600 + 3200 = 5800

Total number of employees in company S and T together

= > 2400 + 3800 = 6200

Required % = [(6200 – 5800)/6200]*100 = 6.45 % = 6 % less
