I got 26000 but they say its wrong

 

cause 

 

The first digit guaranteed to be = 1 

 

The next letter can be all possible = 26

 

Then all the next have to be either ( 0 ,1 , 2 , 3 , 4 , 5 , 6 ,7 , 8 , 9)

 

So : 26 x 10 x 10 x 10 = 26000

LLNN plus Q

 

26*1*10*10*10*2 = 52000 - 10*10*10 = 51000

 

That is assuming the letters have to come first.

 

If you want me to explain why I subtracted 1000 then ask me and I will explain
