Question
Who among the following person sits extreme left end of
the row? Study the following information carefully and answer the below questions. Seven persons- H, I, J, K, L, M, and N are sitting in the linear row facing south. They have different number of pens. L sits third to the left of the one who has 22 pens, neither of them sits on the end of the row. Only one person sits between L and H. I sits second to the right of H. Only two persons are sitting between I and the one who has 15 pens. J sits second to the left of N, both have an odd number of pens. K sits immediate right of the one who has 13 pens. H has an even number of pens. H has 10 pens less than M. L has two pens less than J and one more than K. J has one less than M.Solution
We have, L sits third to the left of the one who has 22 pens, neither of them sits on the end of the row. Only one person sits between L and H. From the above condition, there are three possibilities. Case-1 
Again we have, I sits second to the right of H. From the above condition, Case-2a gets eliminated. Case-1 
Again we have, Only two persons are sitting between I and the one who has 15 pens. J sits second to the left of N, both have an odd number of pens. Case-1 
Again we have, H has 10 pens less than M. L has two pens less than J and one more than K. J has one less than M. From the above condition, case1 shows the final arrangement. Case-1 
I. p2 – 15p + 56 = 0
II. q2 + 2q – 63 = 0
I. 22x² - 97x + 105 = 0
II. 35y² - 61y + 24 = 0
I. 4x² -  15x + 9 = 0
II. 20y² -  23y + 6 = 0
Solve the quadratic equation:
5x² − 13x + 6 = 0
I. 2x2 – 5x - 12 = 0
II. y2 – 11y + 30 = 0
I. 2 x² - 15 + 18 = 0
II. x²- 3 + 2 = 0
...I. 18p²- 21p + 6 = 0   Â
II. 16q² - 24q +9 = 0
I. 99x² + 161 x + 26 = 0
II. 26 y² + 161 y + 99 = 0
Roots of the quadratic equation 2x2 + x – 528 = 0 is
