Here are couple of Questions:

1. Smallest number in English whose letters are arranged in alphabetical order and reverse alphabetical order
             e.g ONE is the number in alphabetical order.

2. Smallest whole number which has letter 'C' in its english spelling?
3. a - b = c
    d / e = f
   g + h = i
   c * f = i
Find a, b, c, d, e, f, g, h, i when they represent numbers from 1-9 each unique.

Answer to 2.

I think there is no whole number the spelling that contains letter "c".

Answer to 3.

a = 9, b = 5, c = 4, d = 6, e = 3, f = 2, g = 1 and h = 7 or g = 7 and h = 1, i = 8

Ctal gave correct answer for no. 3.

I still need answer for q. 1 and q. 3

By the way Ctal, there is a number in english that has letter 'c' in it. (When I say english, it is english, NOT roman number)
