Question 37

What is the remainder when the square of N is divided by 5?
A. When N is divided by 5, the remainder is 3.
B. N is an even integer.

Solution

A : When N is divided by 5, the remainder is 3.

=> $$N=5k+3$$, where $$k$$ is an whole number.

Let $$k=0$$, => $$N=3$$

Thus, when $$N^2=9$$ is divided by 5, remainder = 4

=> Statement A alone is sufficient.

Clearly, second statement is insufficient, as there can be multiple solutions.

=> Ans - (A)
