Please if someone gives a right answer i will Brainliest them.

Answer 1

no its not

lets talk about the divisibility rule of 7

we multiply last number by 2 and subtract it by all remaining numbers

now we have 0325

which is not divisible by 7 so the original number is also not divisible by seven

Answer 2

Answer:

no

Step-by-step explanation:

Subtracting 2 times the last digit from the rest gives a multiple of 7.

So,

$last \: digit = 4 \\ 4 \times 2 = 8$

$8563 - 8 = 8555$

then,

$5 \times 2 = 10$

$8555 - 10 = 8545$

°.° No, it is not divisible because of reminder.
