What is A’s position with respect to B?
From (i) and (ii), if H sits at place no. 5, then D sits at place 1. Also people sitting adjacent to him at place 2 and 8 are students and learn maths. Since H does not study computers and maths, therefore he learns accounts. From (iii), it is clear that the person sitting at place 4 is a student and studies computers. The one sitting at place 3 is a teacher who teaches computers. Also, person sitting at place 6 and 7 will be teacher and student respectively studying accounts. From (iv), A will sit at place no 7. From (v), it is clear that since F is not a student, F sits at either place 3 or 6. C sits immediate left of F, hence, F sits at place no. 3 and C sits at place no. 2. From (vi), E sits at place no. 6. Since B does not study maths, he studies computers and sits at place no. 4. G sits at place no. 8. Now we can answer all the questions with the help of the above arrangement:
I. √(74x-250 )– x=15
II. √(3y²-37y+18)+ 2y=18
I. x2 + 16x + 63 = 0
II. y2 + 2y - 15 = 0
I. 6x² - 23x + 7 = 0
II. 6y² - 29y + 9 = 0
I. 4x2 + 9x - 9 = 0
II. 4y2 - 19y + 12 = 0
I. 22x² - 97x + 105 = 0
II. 35y² - 61y + 24 = 0
I. 2x2- 5x - 33 =0
II. 2y2+ 5y - 25 = 0
I. 3x2 - 14x + 15 = 0
II. 15y2- 34 y + 15 = 0
I. x + 1 = 3√ 9261
II. y + 1 = √ 324
I. 8x² - 78x + 169 = 0
II. 20y² - 117y + 169 = 0
I. 49y2+ 35y + 6 = 0
II. 12x2+ 17 x + 6 = 0
