A fast computer is used to break a ciphertext (A) using columnar transposition cipher that needs 150 attempts, the speed of processor is 4 MIPS (million instructions per second), and each attempt needs 5 instructions. Another computer of speed 3 MIPS is used to break ciphertext (B) using Caesar Cipher that needs 110 attempts, and each attempt needs 4 instructions for ciphertext (B). Determine which ciphertext will be broken first (consider the worst case, i.e. the last attempt is the successful one),
