The value of [ ( 2009! + 2006!)/(2008! + 2007!)] is K . Then value of K/1004 ( [ *] denotes greatest integer function.)

Production of three different flavours soft drinks X, Y and Z over a period of six years has been expressed in the following graph. Study the graph and answer the questions The difference (in lakh bottles) between the average production of flavour X in 2005, 2006 2007 and the average production of flavour Y in 2008, 2009 and 2010 is

int_( equals )^(x)(2010cos2009x-2008sin2009x)backslash dx

The factor of (x^(2010)+y^(2010))^(2010!)-(x^(2009!))^(2010^(2))-(y^(2009!))^(2010^(2)) is: a.x^(2009)b.y^(2009)c.(xy)^(2009!)d.(xy)^(2010)

For which of the following years, the percentage rise or fall in production from the previous year is the maximum for Company Y ? (a) 2007 (b) 2008 (c) 2009 (d) 2010 (e) 2007 and 2010

The value of [ ( 2009! + 2006!)/(2008! + 2007!)] = ( [ *] denotes greatest integer function.)

The variance of the data 2001,2003,2006,2007,2009,2010 is
