The manuscript page contains 90 lines of 40 characters each. The prediction consists of 4 manuscripts and has an informational volume of 45,000 bytes. Indicate the cardinality of the alphabet.

Let’s count how many characters there are:
90 * 40 * 4 = 14400 characters
the cardinality of the alphabet is N
J = 45000 bytes
Let 14400-K
then by the formula
J = K * N
Find N
(45000 * 8) / 14400 = 25
