Answers at the top right. All coupon number is divisible eleval by 3 .. However, the 100 is not divisible by 3. So, logically simple, it is impossible to form coupons to 100. The correct answer is actually not "as much as possible", but it should not be printed coupons at all. The restaurant should revise the system, so as not to be considered as a fraud .. ^^ Reply Delete
