the answer is 40 and here why if you take the multiples of 8 witch are

 8 16 24 32 40 48 56 64 72 80

and the multiples of 10 witch are

10 20 30 40 50 60 70 80 90 100 

you see that the lowest common number that they have is 40

the answer is D because if you had 40 hotdogs with buns you would have no buns or hot dogs left over. so 40 hot dogs is the answer
