Question
If A and I interchange their position, and C and R
interchange their position, then who among the following will be sitting to the immediate left of I? Study the following information carefully and answer the questions given below it. There are eleven persons A, P, C, Q, E, R, G, T, I, V and Y are sitting in a circular table facing towards the centre. Only 5 persons sit between A and I when counted from the right of A. Y sits second to the left of I. T sits third to the left of Y. Only four persons sit between Y and V. Number of letters between E and I in the alphabetical series is same as the number of persons sitting between A and G. Q is an immediate neighbour of V. P sits fifth to the right of Q. E sits second to the left of C.Solution
Only 5 persons sit between A and I when counted from the right of A. Y sits second to the left of I. Only four persons sit between Y and V. Here we get two possibilities Case (1) and Case (2).
Q is an immediate neighbor of V. P sits fifth to the right of Q.
T sits third to the left of Y. E sits second to the left of C. Here Case 1 gets eliminated.
Number of letters between E and I in the alphabetical series is same as the number of persons sitting between A and G.
I. 6 y² + 11 y – 7= 0
II. 21 x² + 5 x – 6 = 0
- For what value of a does the quadratic equation x² + ax + 81 = 0 have real and identical roots?
