Step 3: Solve the same problem, without considering the first letter.
Let's consider the word IBPSPO. As you can see, the alphabet P occurs twice in it. The process basically remains the same as above. However, there will be a slight difference in the way we calculate the answer.
Step 1: Write down the letters in alphabetical order.
The correct order is B, I, O, P, P, S.
Step 2: Find the number of words that start with a superior letter.
Number of words that start with B will be \frac{5!}{2!} = 60.
2!
5!
=60. (We are dividing by 2 because P is repeating itself.)
Step 3: Solve the same problem, without considering the first letter.
We have to find the rank of BPSPO.
This will be the same as the rank of PSPO.
The words above PSPO are the three words starting with O (and ending with PPS, PSP, SPP).
Also, PPOS, PPSO, and PSOP will be above PSPO.
Thus, PSPO will be the 7^\text{th}7
th
word in the list.
So, BPSPO will be the 7^\text{th}7
th
word in the list.
Therefore, the overall rank of the word IBPSPO is 60 + 7 = 67.\ _\square60+7=67.
