Question
How many persons are sitting around the circular
table? Study the following information carefully and answer the below questions A certain number of persons are sitting around the circular table facing the center. G sits second to the left of K. Two persons are sitting between K and J. F and J are sitting adjacent to each other. The number of persons sitting between K and F is the same as between K and E. H sits exactly in the middle of I and F. F sits fifth to the left of E. I does not sit third to the right of J. Not more than one person sits between H and FSolution
We have, G sits second to the left of K. Two persons are sitting between K and J. F and J are sitting adjacent to each other. From the above condition, there are three possibilities 
Again we have, The number of persons sitting between K and F is the same as between K and E. From the above condition, case1 gets eliminated. 
Again we have, H sits exactly in the middle of I and F. F sits fifth to the left of E. I does not sit third to the right of J. Not more than one person sits between H and F. From the above condition, case2 gets eliminated. Case 1a shows the final arrangement 
If x = √7 + √6 and y = √7 - √6 , then the value of is (x2 + y2)/(x3 + y3).
...
If (x + y) = 40, then find the value of (x - 15)5 + (y - 25)5.
- If p = 35 - q - r and pq + r(p + q) = 324, then find the value of (p² + q² + r²).
- If x² - 2x + 1 = 0, then find the value of (x³ + x⁻³)(x + x⁻¹).
- If a 3 + b 3 + c 3 = 62, abc = -6 and (a + b + c) = 5, then what is the value of ab + bc + ac?
If a + b + c = 12 and ab + bc + ca = 50, then find the value of a2 + b2 + c2.
