2) I) 3x = 5y – 4     

II) 5x + 7y – 70 = 0

3) I) x²+ 12x + 32 = 0

II) 3y² – 10y + 7 = 0

4) I) x² = 14641

II) y = √14641

5) I) 2x² +29x +50 =0

Answers :

1) Answer: e)

I) x³ = 2744

X = 14

II) y² – 11y + 60 = 0

(y – 15) (y + 4) = 0

Y = 15, -4

Can’t be determined

2) Answer: a)

3x – 5y = 4–à (1)

5x + 7y = 70–à(2)

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

X = 7, y = 5

x > y

3) Answer: c)

I) x²+ 12x + 32 = 0

(x+ 4) (x+8) = 0

X = -4, -8

II) 3y² – 10y + 7 = 0

3y² – 3y – 7y + 7 = 0

3y(y – 1) – 7(y – 1) = 0

(3y – 7)(y – 1) = 0

Y = 7/3, 1 = 2.33, 1

x < y

4) Answer: d)

I) x² = 14641

X = +121, -121

II) y = √14641

Y = 121

x ≤ y

5) Answer: c)

I) 2x² +29x +50 = 0

2x² +4x+25x +50 = 0

2x(x+2) + 25(x+2) = 0

(2x+25) (x+2) =0

X= -25/2, -2

II) 12y² – 7y +1 = 0

12y² – 4y-3y +1 = 0

4y (3y-1)-1(3y-1) = 0

(4y-1) (3y-1) = 0

Y= ¼, 1/3

X < y

Direction (6-10) :

6) Answer: c)

Total number of Bank employees in all the given years together

= > 1500 + 2500 + 3200 = 7200

Total number of Police in all the given years together

Required % = (7200/4900)*100 = 147 %

7) Answer: b)

The total number of employees in Railway and Income tax department in the year 2015

= > 1200 + 1000 = 2200

The total number of employees in Bank and Medical department in the year 2017

Required difference = 5000 – 2200 = 2800

8) Answer: d)

The ratio of male and female employees in Income tax in 2017= 6 : 5

The ratio of male and female employees in medical department in 2017

= > 1800*(5/9) = 1000

Required sum = 1200 + 1000 = 2200

The total number of employees in all the given department in the year 2016

= > 2500 + 2000 + 1600 + 1200 + 1000 = 8300
