alphbetically means starting arranging with a then e then m
now words with starting a has !5 ways =120ways
so take two letters
now words with ae =!4 ways =24
now words with am=24 ways
total=48
so 49 words will be "aremst"
still total

ASMETR
ae_ _ _ _=4*3*2*1 = 24 ways
ame_ _ _ = 3*2*1 = 6 ways
amre_ _ = 2*1 = 2 ways
are_ _ _ =3*2*1 = 6 ways
arme _ _= 2*1 = 2 ways
ase_ _ _ = 3*2*1 = 6 ways
asme_ _ = 2*1 = 2 ways
total words arranged = 24+6+2+6+2+6+2 = 48
hence, 48th word = asmert
therefore, 49th word = asmetr ans.
