C. 2,600

Answer 1

10*9*26=2,340
B.2,340

Answer 2

Answer:B. 2,340

Explanation:

The number of digits = 10 [0,1,2,3,4,5,6,7,8,9]

The number of alphabets = 26

Now we are given that the code is two different digits followed by a capital letter.

Therefore, the number of different possible codes there are :-

`=\ ^(10)P_2*26=10*9*26=2340`

Hence, there are 2340 different possible codes.
