Giacomo, Brian, and Barbara have each consumed two margaritas during the last two hours. If Giacomo weighs 176 pounds and both Brian and Barbara weigh 138 pounds, then who is probably the most intoxicated?

The correct answer is - Barbara.

Explanation:

BAC or basic alcohol concentration is vary in male to female as females are smaller than men so the total blood is less than the men even the weight is same in both.

This the cause that affects the females to get impaired more than the males and easily get intoxicated even though the weight and amount of the alcohol is similar.

Thus, the correct answer is - Barbara.
