If a positive integer n is divided by 5, the remainder is 3. Which of ...
n divided by 5 yields a remainder equal to 3 is written as follows
n = 5 k + 3 , where k is an integer.
add 2 to both sides of the above equation to obtain
n + 2 = 5 k + 5 = 5(k + 1)
The above suggests that n + 2 divided by 5 yields a remainder equal to zero. The answer is B.

If a positive integer n is divided by 5, the remainder is 3. Which of ...
To find the number that yields a remainder of 0 when divided by 5, we need to understand the concept of remainders and how they are affected by addition and subtraction.
Let's assume the positive integer n is divided by 5, and the remainder is 3. This can be expressed as:
n = 5a + 3
where a is a positive integer representing the quotient.
To find a number that yields a remainder of 0 when divided by 5, we need to find a value of n that satisfies the equation:
n = 5b + 0
where b is a positive integer representing the quotient.
Let's analyze the answer options:
a) n + 3: Adding 3 to the number n will not change the remainder when divided by 5. It will still be 3, so this option does not yield a remainder of 0.
b) n + 2: Adding 2 to the number n will increase the remainder by 2 when divided by 5. Since the remainder was originally 3, adding 2 will result in a remainder of 0. This option satisfies the condition and yields a remainder of 0.
c) n - 1: Subtracting 1 from the number n will decrease the remainder by 1 when divided by 5. Since the remainder was originally 3, subtracting 1 will result in a remainder of 2. This option does not yield a remainder of 0.
d) n - 2: Subtracting 2 from the number n will decrease the remainder by 2 when divided by 5. Since the remainder was originally 3, subtracting 2 will result in a remainder of 1. This option does not yield a remainder of 0.
e) n + 1: Adding 1 to the number n will increase the remainder by 1 when divided by 5. Since the remainder was originally 3, adding 1 will result in a remainder of 4. This option does not yield a remainder of 0.
Therefore, the only option that yields a remainder of 0 when divided by 5 is option b) n + 2.
