Question

Three consecutive natural numbers are added and their sum is divided by 3. What is the remainder obtained?

• A. 0
• B. 1
• C. 2
• D. 4

Answer 1

The correct option is A

0

Let the three consecutive numbers be m, m + 1 and m + 2.
Sum of these three numbers $=m+m+1+m+2=3m+3=3(m+1)$
$\Rightarrow$ Their sum is completely divisible by three.
$\therefore$ Remainder will be 0.
