Question
Which of the following statement is
true? Study the following information carefully to answer the given questions Eight friends- Deepak, Pooja, Sonal, Ankit, Ritu, Mohit, Naman, and Neelam live on different floors of a building but not necessarily in the same order. The bottommost floor is number 1 and the uppermost floor is no. 8. All are living on different floors. Pooja lives just below to Deepak and both are living above the floor no. 5. Pooja lives three floors above to Ankit, who is not adjacent to Ritu and Mohit.Naman lives two floors below Ankit.There are only two persons live between the one who is immediate above to Neelam and the one who is adjacent to Mohit. Where Mohit lives above Neelam.Sonal lives somewhere above to Ritu, but not immediately above.Solution
We have, Pooja lives just below to Deepak and both are living above the floor no. 5. Pooja lives three floors above to Ankit, who is not adjacent to Ritu and Mohit. Naman lives two floors below Ankit. 
1 Ritu Naman Case-II is invalid because Sonal and Ritu do not live adjacently. Based on the above information we have a final arrangement 
I. 8y2 - 2y - 21 = 0
II. 2x2 + x - 6 = 0
I. 4x² -  15x + 9 = 0
II. 20y² -  23y + 6 = 0
I. 40x² + 81x + 35 = 0
II. 63y² + 103y + 42 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 20x + 96 = 0
Equation 2: y² - 18y + 72 = 0
I:Â x2Â - 33x + 242 = 0
II:Â y2Â - 4y - 77 = 0
I. x2 – 13x + 40 = 0
II. 2y2 – 15y + 13 = 0Â
I. 5x² = 19x – 12
II. 5y² + 11y = 12
I. 81x - 117√x + 40 = 0
II. 81y - 225√y + 136 = 0
I. x² - 19x + 84 = 0
II. y² - 25y + 156 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 24x + 135 = 0
Equation 2: y² - 26y + 153 = 0
