Answers :

Direction (1-5) :

1). Answer: e)

I) x² – 8x – 48 = 0

(x – 12) (x + 4) = 0

X = 12, -4

II) 2y² + 9y – 26 = 0

2y² – 4y + 13y – 26 = 0

2y(y – 2) + 13(y – 2) = 0

(2y + 13) (y – 2) = 0

Y = -13/2, 2 = -6.5, 2

Can’t be determined

2). Answer: d)

I) 3x² + 27x + 52 = 2x² + 14x + 16

3x² – 2x² + 27x – 14x + 52 – 16 = 0

X² + 13x + 36 = 0

(x + 9) (x + 4) = 0

X = -9, -4

II) y² = 16

Y = 4, -4

x ≤ y

3). Answer: c)

I) 5y³ = (112 ÷ 7) + 3y³

5y³ – 3y³ = 112/7

2y³ = 16

Y³ = 8

Y = 2

II) y^1/3 × y^1/3 × 17 = 51 ÷ y^1/3

y^1/3 × y^1/3 × y^1/3 = 51/17

y^{1/3 + 1/3 + 1/3} = 3

y = 3

x < y

4). Answer: a)

8x – 5y = 25 –à (1)

5x + 3y = 34 –à (2)

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

X = 5, y = 3

X > y

5). Answer: e)

I) 5x² + 18x + 16 = 0

5x² + 10x + 8x + 16 = 0

5x (x + 2) + 8(x + 2) = 0

(5x + 8) (x + 2) = 0

X = -8/5, -2 = -1.6, -2

II) 4y² + 18y + 18 = 0

4y² + 12y + 6y + 18 = 0

4y(y + 3) + 6(y + 3) = 0

(4y + 6) (y + 3) = 0

Y = -6/4, -3 = -1.5, -3

Can’t be determined

Direction (6-10) :

6). Answer: c)

The total number of students studied in the institution Q from Chennai and Pune together

= > 270 + 220 = 490

The total number of students studied in the institution S from Mumbai and Kolkata together

= > 300 + 290 = 590

Required difference = 590 – 490 = 100

7). Answer: a)

The total number of students studied from Chennai in all the given institution together

= > 450 + 270 + 350 + 310 + 290 = 1670

The total number of students studied from Kolkata in all the given institution together

= > 340 + 360 + 270 + 290 + 300 = 1560

Required ratio = 1670: 1560 = 167: 156

8). Answer: d)

The total number of students studied from Delhi in all the given institutions together

= > 280 + 330 + 320 + 290 + 330 = 1550

Required average = 1550/5 = 310

9). Answer: e)

Total number of students studied in institution P, R and S together from Chennai

= > 450 + 350 + 310 = 1110

Total number of students studied in institution Q and R together from Delhi

= > 330 + 320 = 650

Required % = (1110/650)*100 = 170 %

10). Answer: b)

Total number of students studied in institution Q and S together from Mumbai

= > 400 + 300 = 700

Total number of students studied in institution P and T together from Kolkata

= > 340 + 300 = 640

Required % = [(700 – 640)/640]*100 = 9 % more
