Two texts contain the same number of characters, the first text is composed in an alphabet with a capacity of 4 characters

Two texts contain the same number of characters, the first text is composed in an alphabet with a capacity of 4 characters, the second is 16 characters. How many times the amount of information in these texts differs.

We are looking for the formula for how many 4 characters take: N1 = 2 ^ i1 8 = 2 ^ 3 => i1 = 3 bits Now 16 characters: N2 = 2 ^ i2 16 = 2 ^ 4 => i2 = 4 bits Because the amount of text k is the same, then we get (k * i1) / (k * i2) = i1 / i2 = 3/4 times
