Every letter of the group XYZA is replaced by the letter standing five places ahead of it in the English alphabet, the alphabet being treated as running on from Z round to A again. What is the resulting group of letters?

X is the 24th letter; five ahead runs Y, Z, A, B, C, so X gives C. Y likewise gives D, Z gives E and A (1st) gives F (6th). The group is CDEF. BCDE is the result of moving only four places ahead, DEFG of moving six, and STUV of moving five places behind instead of ahead.
