Total words

= 11

No. of words left, if we exclude all s

= 7

Four S will be treated as

1

block.

No. of ways in which all four S come consecutively

= \frac{( 11 - 4 + 1 )!}{4 ! 2 !}

(since I are repeated

4

times and P times So total no. of ways are divided by

4! 22!

)

∴

No. of ways

= \frac{8 !}{4 ! 2 !} = 840

∴ 840
