See words in APHABETICAL ORDER ARE
A, B ,E,R,S,U
If we fix A and rest letters(BERSU)can be arranged in 5! ways=120-->It crosses 49 and hence we need to fix B too.
Now with A and B fixed...rest letters ERSU can be arraned in 4!ways=24
SO 24 words can be reacged by AB...anythinghere
Now if we move ahead of B...E comes So keeping
A and E fiexed..remailning letters BRSU can be arranged in 24 ways.
Total words formed=48 when A B/E have been take care of
Now next in sequence after E is R
Fixing A nd R...we need the first word in alphabetical sequence out of re,maining letters BESU....which is BESU
hence 49th word= AR BESU
