The average of 4 consecutive odd numbers a, b, c, d is 54.what is the product of a and c

• let nos are 2x+1,2x+3,2x+5,2x+7
  a/c problem (2x+1+2x+3+2x+5+2x+7)/4=54,x=25
  a=51,b=53,c=55,d=57
  a*c=51*55=2805

• let the 4 nos. be x,x+2,x+4,x+6
  So x+x+2+x+4+x+6=4*54
  Solving this,x=51
  So 4 nos.are 51,53,55,57
  therefor 51*55=2805

• let no.s b n,n+2,n+4,n+6
  given,n+n+2+n+4+n+6=208
  v get,n=51
  a*c=51*55=2805

• a+2a+3a+4a/4=54
  10a=216
  a=21.6
  c=3*21.6=64.8

• a=9, b=11, c=13, d=15
  so, ac=15*9=135

• 51+53+55+57=216
  216/4=54
  therefore,a=51,b=53,c=55,d=57
  a*c=51*55=2805
