'HC' is related to 'KQ' in a certain way. Similarly, 'OG' is related to 'AB' in the
same way. To which of the following is 'RK' related following the same pattern?
1) TJ 2) SI 3) TI
4) HD 5) IM

• H...C => K...Q
  8...3 => 11...17
  THEREFORE 83-1=82 => 11+17=28
  82 => 28
  NOW
  O...G => A...B
  15...7 => 1...2
  THEREFORE 15+7=21 => 12
  21 => 12
  HENCE
  R...K => ?
  18...11 =>?
  18+11=29
  29-1 => 28 => 82+1 => 83
  i.e. 8th alpha + 3rd alpha = HD
  THEREFORE RK => HD
