1) if x > y                 2) if x >= y                3) if x < y                4) if x <= y                 5) if x = y or relationship between x and y cannot be determined.

Q1. I. x^2 – 26x + 169 = 0                II. y^2 – 28y + 196 = 0

Q2. I. 2x^2 + 6x – 36 = 0                II. 2y^2 + 25y + 78 = 0

Q3. I. 7x^2 + 104x + 169 = 0                II. y^2 + 10y – 39 = 0

Directions: Each question below is followed by two statements A and B. You have to determine whether the data given in the statement is sufficient to answer the question. You should use the data and your knowledge of mathematics to choose between the possible answers. Give answer:
1) if the statement A alone is sufficient to answer the question, but the statement B alone is not sufficient.
2) if the statement B alone is sufficient to answer the question, but the statement A alone is not sufficient.
3) if the both statement A and B together are needed to answer the question.
4) if either the statement A alone or B alone is sufficient to answer the question.
5) if you cannot get the answer from the statements A and B together, but needed even more data.

Answer & Explanation
  1. 3;
  2. x^2 – 26x + 169 = 0

(x – 13)^2 = 0

x = 13

  1. y^2 – 28y + 196 = 0

(y – 14)^2 = 0

y = 14

x < y

 

  1. 2;
  2. 2x^2 + 12x – 6x – 36 = 0

2x (x + 6) –6 (x + 6) = 0

(x + 6) (2x – 6) = 0

x = –6, 3

 

  1. 2y^2 + 12y + 13y + 78 = 0

2y (y + 6) + 13 (y + 6) = 0

(y + 6 ) (2y + 13) = 0

y = –6, -13/2

x > y

 

  1. 5;
  2. 7x^2 + 13x + 91x + 169 = 0

(x + 13) (7x + 13) = 0

x = – 13, -13/7

 

  1. y^2 + 13y – 3y – 39 = 0

(y – 3) (y + 13) = 0

y = 3, – 13

Relationship between x and y cannot be established.

 

  1. 5;
  2. x^2 – 8x + 2x – 16 = 0

(x + 2) (x – 8) = 0

x = – 2, 8

  1. 3y^2 + 22y + 24 = 0

3y 2 + 4y + 18y + 24 = 0

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

y = –6, -4/3

Relationship between x and y cannot be established.

 

  1. 1;

From A, we get,

P = 100*SI/R*T = Rs. 1200

 

  1. 5;

P + Q + R + S = 86

From A, P + Q + S = 24 × 3 = 72 R = 86 – 72 = 14

 

From B, R + S = 28 × 2 = 56

We cannot get Q’s present age from both statements.

 

  1. 2;

From statement B, work done by Q = 18 × 4/3 = 24 days.

 

  1. 2;

Out of 14 players, let us element 2 particular player

which are excluded. Now, there are 12 players for selection of these 12, three have to be included in team always. Thus remaining players are (12 – 3) = 9 and the required players for team (10 – 3) = 7. Now,

selection cannot be done in

9C7 ways.

 

9C7 = 9!/7!2! = 36 ways.

 

  1. 1;

Let the present age of mother and daughter be 7x and 3x year.

7x – 4/3x – 4 = 5/2

14x – 8 = 15x – 20

x = 12

 

Mother’s age five years from now = 12 × 7 + 5

= 84 + 5 = 89 year

 

  1. 5;

In Set A, 9x + 2(1 + 2 + ….. + 8) = 657

9x + 8*9*2/2 = = 657

9x + 36 × 2 = 657

x = 65

 

lowest number of another set = 65 + 18 = 83

 

Sum of seven consecutive number of another set

= 7x + (1 + 2 + 3 + 4 + 5 + 6) × 2

= 7x + 6*7*2/2

= 7x + 21 = 83 × 7 + 42 = 623

 

  1. 4;

First arrange the 7 boys in a row in 7P7 = 7! ways.

Then, there are 8 gaps between them. Now 5 girls can be

arranged in 8 gaps in P5

8 ways.

Required number of ways of arrangement = 7! × 8P5 = 7 ! * 8 !/5!

= 8! × 7 × 6 = 42 × 8 !
