If L sits second to the left of I then how many seats are between L and E when counted from the right of E?
STEP I: M sits third to the left of I who sits an immediate neighbour of K. Three persons sit between A and K who sits second to the left of C. As per these statements, we can say that there are three possible cases and the arrangement will look like this: STEP II: E sits to the immediate left of G who sits second to the left of M. Both E and A sit adjacent to each other. The number of persons sits between G and K is one less than the number of persons sits between K and E when counted from the right of both G and K respectively. At least one person sits between C and E when counted from the right of C. As per these statements, CASE I and CASE III get eliminated and we continue with CASE II and the final arrangement will look like this:
If 2y . cos θ - x . sin θ = 0 and 2x . sec θ - y . cosec θ = 3, what is the value of x² + 4y²?
If P, Q, R, S are the vertex of a cyclic quadrilateral. Find the value of
