In a certain code FIRE is coded as DGPC. What will be the last letter of the coded word for SHOT.

D is used for F.
G is used for I.
P is used for R.
and
C is used for E. Thus, it is clear that each letter of the word FIRE stands for each corresponding letter of the coded word DGPC two places ahead. By applying the same principle, the letters QFMR will stand for SHOT. Hence, the last letter of the coded word is R.
