Read Solution (Total 7)
-
- source: internet
purpose: ease of understanding
Arranging the words of waiting in Alphabetical Order : A,G,I,I,N,T,W
Start with A_ _ _ _ _ _ This can be arranged in 6!/2! ways=720/2=360 ways
so can't be arranged starting with A alone as it is asking for 32nd word so it is out of range
AG_ _ _ _ then the remaining letters can be arranged in 5!/2! ways so,120/2=60 ways. Out of range as it has to be within 32 words.
AGI _ _ _ Now the remaining letters can be arranged in 4! ways =24
AGN _ _ _ _ can be arranged in 4!/2! ways or 12 ways
so,24+12 =36th word so out of range. So we should not consider all the words start with AGN
now AGNI_ _ _can be arranged in 3! ways =6 ways
so 24+6=30 within range
Now only two word left so, arrange in alphabetical order.
AGNTIIW - 31st word
AGNTIWI - 32nd word - 9 years agoHelpfull: Yes(13) No(3)
- Sorry i did wrong in my 1st solution,
the answer will be AGNIIWT
fixing AGI we have AGI IWTN no. of arrangements =4!=24 ways
again fixing AGN TWII 4!/2!==4*3=12 ways
it is crossing 32 as sum is 36(24+12)
so word lie inside this AGN ,fixing AGNI TWI we have 3!=6 ways
so 30 words.now do manually 31st-AGNIITW
