• A. Yes divisible by $15$
• B. Not divisible by $15$
• C. $4125$
• D. $4375$

Answer 1

Answer: (A), (C)

$4125$

The quotient when $12375$ is divided by $3$ is $4125$.

For a number to be divisible by $15$, it must be divisible by $3$ as well as $5$.
For a number to be divisible by $3$, sum of its digit must be divisible by $3$.
For a number has $0$ or $5$ at it's unit place then the number is divisible by $5$.

The number $4125$ is divisible by $15$ because it has $5$ in its unit place which makes it divisible by $5$ and sum of digits of the number is $12$ that makes it divisible by $3$ as well.
