Answer & Explanation
  1. 1;

x = sqroot(1369) = 37……………….. (I)

y = cuberoot(29791) = 31 ………………. (II)

x > y

 

  1. 3;

Equn. (I) ×4 + equn (II) ×3

32 x – 12 y = 124

15 x + 12 y = 252

_____________

47 x = 376

4

x = 8 and from this y = 11

x < y

 

  1. 2;

20 x^2 – 35 x – 44 x + 77 = 0

5 x (4 x – 7) – 11 (4 x – 7) = 0

(4x – 7) (5 x – 11) = 0

x = 7/4, 11/5

 

4 y^2 + 16 y – 7 y – 28 = 0

4 y (y + 4) – 7 (y + 4) = 0

(4 y – 7) (y + 4) = 0

y = – 4, 7/4

x >= y

 

  1. 4;

6 x^2 + 8 x + 21 x + 28 = 0

2x (3 x + 4) + 7 (3x + 4) = 0

(3x + 4) (2 x + 7) = 0

x = -4/3, -7/2

 

6 y^2 + 3 y + 8 y + 4 = 0

3 y (2 y + 1) + 4 (2 y + 1) = 0

(3 y + 4) (2 y + 1) = 0

y = -4/3, -1/2

x <= y

 

 

  1. 5;

x^2 + 9x – 6 x – 54 = 0

x (x + 9) –6 ( x + 9) = 0

x = 6, –9

 

y^2 + 11 y – 7 y – 77 = 0

y (y + 11) – 7 (y + 11) = 0

(y – 7) (y + 11) = 0

y = 7, –11

i.e. No relation between x & y

 

  1. 2;

B male = 554400/16 * 9 = 311850

 

  1. 1

F(Ad) = 302820/21 * 13 = 187460

 

  1. 3

Cmale = 369900/9 * 4 = 164400

Req% = 164400/258000 * 100 = 63.72%

 

  1. 4

Diff = 281520/17 * (11 – 6) = 16560 * 5 = 82800

 

  1. 5

A(Fe) = 333500/23 * 11 = 159500

B(Fe) = 554400/16 * 7 = 242550

 

Req% = 159500/242550 * 100 = 65.76%
