If x belongs to the set of residues modulo 6 and `3 + x -= 2` (mod 6), then x = ________.A. 1B. 3C. 4D. 5 |
|
Answer» Correct Answer - D `Z_(6) = {0,1,2,3,4,5}` and `x in Z_(6)`. Given, `3 + x -= 2` (mod 6) `rArr 3 + x - 2` is divisible by 6 `rArr x + 1` is divisible by 6 x = 5 satisfies the above conditions. |
