Question

To encode a message, James first replaces each letter within the message with its

corresponding number, where A = 1, B = 2, · · · , Y = 25, and Z = 26. Next, James
multiplies each number by 3 and then subtracts 5, and continues this process a total
of n times. For example, when n = 2 the letter D is encoded to the number 16.
If James encoded a four letter message to the four numbers 367 205 853 1339, what
is the value of n that he used?
(A) 2 (B) 3 (C) 4 (D) 5 (E) 6

Answer 1

E) (6)

Explanation:

If you used rule of x^2/x^3 x cosh = x/100

You would contine this by using radionuklider thereom, you would obtain x/100=600. If this is further simplified tou would find the x=6, therefore y=18 accordingly.

Answer 2

56
