Question

If all the words formed from the letters of the word HORROR are arranged in the opposite order as they are in a dictionary, then the rank of the word HORROR is

• A. $56$
• B. $57$
• C. $58$
• D. $59$

Answer 1

The correct option is C $58$

Words starting with R are $\frac{5!}{2!.2!}=30$
Words starting with O are $\frac{5!}{3!}=20$
Words starting with HR are $\frac{4!}{2!.2!}=6$
The word prior to HORROR in the reverse order is HORRRO.
Hence, the rank of the word HORROR is
$30+20+6+1+1$
$=58$
