Question
If all the persons are arranged in alphabetical order
in the clockwise direction with respect to A, then how many persons remain unchanged in their position (Excluding A)? Study the following information carefully and answer the below questions  Eight persons – A, B, C, D, E, F, G and H are sitting in the square table such that all of them are facing towards the center. Four persons are sitting in the middle of the sides of the table and four persons are sitting at the corner of the table. All the information is not necessarily in the same order.  A sits second to the left of G, who sits at one of the corner of the table. H sits either to the immediate right or to the immediate left of A. D sits opposite to the one who sits second to the left of C. C sits in the middle of the sides of table. D is neither the immediate neighbor of G nor A. E is the immediate neighbor of either of A or F, but not the both. B sits second to the left of F.Solution
A sits second to the left of G, who sits at one of the corner of the table. H sits either to the immediate right or to the immediate left of A. From the above condition, there are two possibilities.
D sits opposite to the one who sits second to the left of C. C sits in the middle of the sides of table. D is neither the immediate neighbor of G nor A
E is the immediate neighbor of either of A or F, but not the both. B sits second to the left of F. From the above condition, case1 gets eliminated. Â Case 2 shows the final arrangement. 
 = ? if a2 + b2 + c2 = 2(3a -5b -6c)-70 , then a-b-c = ?
If
= -2 then find If a = (√2 - 1)1/3, then the value of (a-1/a)3 +3(a-1/a) is:
If x² + px + q = 0 has roots 4 and -3, find the values of p and q.
Calculate the value of the expression: {2 X (P3Â - Q3) - 30 X P X Q} if (P - Q) = 6 and (P2Â + Q2) = 80
- Find the value of the expression {(4096) n /4  × 8 3n + 1 }/{(512) n  × 8 n – 1 }.
If, 4x2 + y2 + 12x + 6y + 18 = 0, then find the value of (2x + y)/(y + 6x).

If [8(x + y)3 – 27(x – y)3] ÷ (5y – x) = Ax2 + Bxy + Cy2, then the value of (A2 - 2B + 3C)...
