10A+B+C+D+E = 10A +F
B+C+D+E = F
since all are different and F is to be maximized
let B=0
D =1
e =2
F =9
hence, C can be 6.
Its do or die this time!
Practise, practise and practise.

Clearly the answer is [spoiler]6 [C][/spoiler]

Explanation
A B
+ C
+ D
+ E
_____

A F
_____
Since A is left unaltered we can conclude that the carry part of addition is 0
=> B+C+D+E <=9
For max C and different BCDEA we have

0+1+2+C = 9
=> C = 6

Hope it helps!!
If you feel like it, hit thanks :)
