• ans:a
  357:73(last digit and first digit)
  429:94
• 10 years agoHelpfull: Yes(22) No(1)
• remove the middle numbers and interchange the first and last element
  so answer is A
  357:73=>37:73=>73:73
  same as
  429:94=>49:94=>94:94

• ans:a
  357:73::x:y
  if we go for product of means=product of extremes we find this the best choice.
  i.e. closer to 1.
  a>357:73::429:94
  (73*429)/(357*94)=.93
  b>357:73::201:21
  (73*201)/(357*21)=1.97
  c>357:73::138:38
  (73*138)/(357*38)=0.74
  d>357:73::93:39
  (73*93)/(357*39)=0.48
