The letters in the word "places" are permuted in all possible ways and arranged in the alphabetical order.
total permutations= 6! = 720
720/6 = 120 words,
first 120 will start with letter a. So 48th letter will start with a.
So FIRST LETTER IS A.
if we keep a in first place, we will have 5! permutations with c,e,l,p and s.
5!/5 = 120/5 = 24 words.
First 24 words(0-24) will be with first two letters as AC
Next 24 words(25-48) will be with first two letters as AE.
So 48th word has first two letters as AE.
48th letter is the last word with first two letters as AE.
So rest of the letters of the word will be arranged from last to first: S-P-L-C
So 48th word is AESPLC

Answer:THE ANSWER IS AESPLC
Step-by-step explanation:
PLACES
alphabatic order is ; A E S P L C
the number of words startwith A is A 5 4 3 2 1=126
A is the first term
the number of terms start with AC 4 3 2 1 =24
the number of words start with AE 4 3 2 1= 24
=48 SO STOP HERE
THE first leters in the 48 th word is AE then write after all are in the order of alfabatic order then we get AECLIPS
BUT WE HAVE TO DO one thing here arengethe word CLIPS
IS IN OPOSITE AS SPILC .
THEN THE FINAL ANSWER IS
(AESPLC)
