Some of mathematical operations are given below choose the expression which is mathematically correct. If A = 4, B = 6, and C = 8, what is the value of ((A + B) × C) mod 97?
80
Substitute the values A = 4, B = 6 and C = 8.
A + B = 4 + 6 = 10.
(A + B) × C = 10 × 8 = 80.
x mod 97 is the remainder when x is divided by 97; since 80 is less than 97, 80 mod 97 = 80.
Check: 80 = 97 × 0 + 80, so the remainder is 80.
Hence, 80.
