If the letters of the word BAZAR are arranged in dictionary order, then what is the 50th word ?A. ZAABRB. ZBAARC. ZBRAAD. ZAARB

Answer» Correct Answer - D
With A at first place, rest 4 places will be arranged in 4! Ways so, Number of words begin with A = `4! = 24` Similarly with B at first place,
Number of words begin with `B = (4!)/(2!) = 12` [As there are two `A_(s)`]
Number of words begin with `R = (4!)/(2!) = 12`
Thus, 48 words have starting letter A, B, and R. So, 49th word will be ZAABR and 50th word will be ZAARB
