When 'n' is divisible by 5 the remainder is 2. What is the remainder when \( \Large n^{2} \) is divided by 5?

A) 2
B) 3
C) 1
D) 4

Correct Answer:




D) 4

Description for Correct answer:
\( \Large \frac{n}{5} \)\( \Rightarrow \) remainder 2

If we put n = 7 Then it satisfies above situation

So n = 7

\( \Large \frac{n^{2}}{5}=\frac{7^{2}}{5}=\frac{49}{5} \)

\( \Rightarrow \) remainder = 4
