Question
How many floors are there between D and H?
Study the following information carefully and answer the below questions Eight persons- A, B, C, D, E, F, G, and H are living in the eight-storey building. The lowermost floor is numbered as one and the topmost floor is numbered as eight. No two persons live on the same floor. G lives three floors above E who lives on an odd numbered floor. F lives above G but not on an odd numbered floor. The number of floors above F is the same as below H. B lives immediately above D. The number of floors between D and A is the same as between H and E. C lives below A.Solution
We have, G lives three floors above E who lives on an odd numbered floor. From the above condition, there are three possibilities.
Again we have, F lives above G but not on an odd numbered floor. From the above condition, case1 gets eliminated.
Again we have, The number of floors above F is the same as below H. From the above condition, case3a gets eliminated.
B lives immediately above D. The number of floors between D and A is the same as between H and E. C lives below A. From the above condition, case2 gets eliminated.

In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between 'p' and 'q' and choose...
I. 20y² - 13y + 2 = 0
II. 6x² - 25x + 14 = 0
If the roots of the quadratic equation 6m² + 7m + 8 = 0 are α and β, then what is the value of [(1/α) + (1/β)]?
I. x² - 33x + 270 = 0
II. y² - 41y + 414 = 0
I. 2x2 – 25x + 33 = 0
II. 3y2 + 40y + 48 = 0
I. 165x² + 97x + 10 = 0
II. 117y² - 163y + 56 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 97x² - 436x + 339 = 0
Equation 2: 103y² - 460y + 357 = 0
I. 2b2 - 37b + 143 = 0
II. 2a2 + 15a - 143 = 0
- Determine the value of m so that the equation x² + mx + 25 = 0 has equal and real roots.
