If K≡ 5 (mod 11), then all the possible non-negative values of K are :
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → {5, 16, 27, 38, 49, ........}
The given modular congruence is,
$k≡5(mod\,11)$
⇒ General solution = $11n + 5$ ($n≥0$ and $n∈Z$)
$∴k=\{5, 16, 27, 38, 49, ........\}$
