Question
If D is related to A and B is related to C in a certain
way. Then, who among the following is related to F? Study the following information carefully and answer the below questions A certain number of persons are sitting around the circular table facing the center. F sits second to the left of G. Only two persons are sitting between G and C. Only one person sits between C and B. B does not sit adjacent to G. The number of persons sits between G and B is the same as the number of persons sit between G and E. The number of persons sits between F and C is one less than the number of persons sits between E and B, when counted to the right of both F and B respectively. B sits exactly in the middle of A and C. D sits second to the right of A.Solution
We have, F sits second to the left of G. Only two persons are sitting between G and C. From the above condition, there are two possibilities. 
Again we have, Â Only one person sits between C and B. B does not sit adjacent to G. The number of persons sits between G and B is the same as the number of persons sit between G and E. 
Again we have, Â The number of persons sits between F and C is one less than the number of persons sits between E and B, when counted to the right of both F and B respectively. B sits exactly in the middle of A and C. D sits second to the right of A. From the above condition, case1 gets eliminated. Case 2 shows the final arrangement. 
I. 15y2 + 26y + 8 = 0
II. 20x2 + 7x – 6 = 0
I. x2 – 10x + 21 = 0
II. y2 + 11y + 28 = 0
- If the quadratic equation x² + 18x + n = 0 has real and equal roots, what is the value of n?
I. 35x² - 24x – 35 = 0
II. 72y² - 145y + 72 = 0
I. 2x2 – 5x – 12 = 0
II. 2y2 + 13y + 20 = 0
I. 22x² - 97x + 105 = 0
II. 35y² - 61y + 24 = 0
I. 4x2 + 3√7 x-7 =0
II. 7y2 + 4√7 y-5=0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 11x² - 93x + 88 = 0
Equation 2: 13y² + 118y + 93 = 0
I. 5x² - 28x + 39 = 0
II. 2y² - 13y + 20 = 0
I. 4x2 + 9x - 9 = 0
II. 4y2 - 19y + 12 = 0
