1) the way u solved will give the ans < 2%

63) the function can be max either at its boundary or at the point where its first derivative = 0. (as the derivative of the func will not be necessarily 0 at its boundary. we check for maxima or minima at extremum by putting in the values in the func)
      So option (c)

93) use L hospital rule Lim f(x)/x = lim f ' (x)/1 = 0 (in both case as x --> infinity)
