Answer 2

ANSWER: 126th Person

EXPLANATION: The first person to get both the $10 coupon alloted for 7th person and $25 coupon alloted for 18th person is the 126th person. This is proved by a simple mathematics as the number 126 is the first number to bee divisible by both 18 and 7. Hence it is proved that the 126th person will be the first person to receive both the coupons.
