Qt A

567213560 when divided by 8

8's divisibility rule:
if the last three digits are divisible by 8, then the whole number is divisible by 8

consider the last three digits 560, when divided by 8, the remainder will be 0

Qt B

297845786 when divided by 7

7's divisibility rule:
Take the last digit of the number you're testing and double it. Subtract this number from the rest of the digits in the original number. If this new number is either 0 or if it's a number that's divisible by 7, then you know that the original number is also divisible by 7.

Here, the last digit is 6, and its double is 12.

When subtracting 12 from 29784578, we will get 29784566, which is divisible by 7.

You can use the calculator as well.

Qt A = Qt B

The solution requires the use of divisibility rules of 7 and 8. We get the remainders equal to zero for both quantities. Hence the answer is C. You may want to see the detailed solution shared by rx10
