letters starting with
AHK -> 4! = 24
AHN -> 4! = 24
so the total = 48, we need 7 more, so we will fix one more letter
AHSK -> 3! =6

so the total is 48+6 = 54
so the 55th letter will be
AHSNKUV

The letters of SHUVANK if arranged in alphabetical order we get: A H K N S U V
The first letter will be A and the remaining 6 letters can be arranged in 6! Ways. This is far ahead of our requirement of 55th word.

If we take the first two alphabets A and H, the remaining five letters can be arranged in 5! Ways ie 120 ways. This again is head of our requirement of 55th word.

If we take the first three alphabets A H K then the remaining four letters can be arranged in

4! Ways ie 24 ways.

The next arrangement can be A H N. Again the remaining four letters can be arranged in 4! Ways ie 24 ways.

Next arrangement of letters will be A H S K and the remaining three letters can be arranged in 3! Ways.

We now have, alphabets starting from A H K can be arranged in 24 ways

Alphabets starting from A H N can be arranged in 24 ways

Alphabets starting from A H S K can be arranged in 6 ways. Totalling 54 ways

Hence the 55th arrangement of word will be AHSNKUV
