Answer 2

Answer:

No, it is not divisible by 11.

Step-by-step explanation:

Divisibility by 11:

Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number.

Here, applying the rule,

(9+2+3+5)-(4+7+5)

=3 which is not divisible by 11.

Hence, given number is not divisible by 11.
