Question

# Which of the following numbers is divisible by $$12$$?

A
3781
B
3982
C
9853
D
2712

Solution

## The correct option is D $$2712$$We know the divisibility rule: If a number is exactly divisible by both $$3$$ and $$4$$, then the number is divisible by $$12$$.Here, the sum of the digits is $$2 + 7 + 1 + 2 = 12$$. $$12$$ is multiple of $$3$$, so the number is multiple of $$3$$.$$2712$$, last $$2$$ digits $$12$$ exactly divisible by $$4$$, so the number is divisible by $$4$$.So, the number $$2712$$ is divisible by both $$3$$ and $$4$$, the number is divisible by $$12$$.Mathematics
