Here's your Answer...
Words starting with A are formed with the letters 2I's,2N's A,E,X,M,T,O
Number of word formed by these letters are
= 10!/2! × 2!
=> 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1)/ 2 × 2
=> 907200.
Now,
The word starting with letter E, I, M, N, O,T, X will form.
Therefore,
Number of words before the first word starting with E is formed.
