- et me explain u the procedure
first arrange the words in alphabetical order
E I N O R S
let us find all the words which can be made using E as it the first one
E _ _ _ _ _
these five words can be arranged in 5! (five factorial i.e 5*4*3*2*1 = 120 ) more than 36
therefore we need to consider all words of e series
for eg. E I _ _ _ _ i.e 4! (4*3*2*1= 24)
then we consider next series
E N _ _ _ _
these will be similarly 24 .therefore total 48 word
sowe get back to words of series E I N _ _ _ i.e 3! = 6
total 30
next series is E N I _ _ _
COUNT IT MANUALLY NOW
enisro IS THE ANS I GUESS
