How would you determine which road to take?

Answer: Ask each brother, "If you were your brother, which road would you say leads to eternal happiness?"
Explanation: **Let's say the path on the right leads to eternal happiness. After you ask your question, both brothers will tell you the exact same thing: "He would say the left path leads to eternal happiness." In either case ... you would pick the opposite of what they both say because one is telling the truth about it being a lie, and one is lying about it being the truth.

Can they all get across the bridge in 15 minutes or less?

Nō. 11 During a recent census, a man told the census taker that he had three children. When asked their ages, he replied, "The product of their ages is 72. The sum of their ages is the same as my house number." The census taker ran to the man's front door and looked at the house number. "I still can't tell," she complained. The man replied, "Oh that's right, I forgot to tell you that the oldest one likes chocolate pudding." The census taker then promptly wrote down the ages of the three children. How old are they?

Answer: The three kids are 3, 3, and 8 years old.
Explanation: The key to this brain teaser is that the census taker looks at the house number. In other words, she knows the sum of the children's ages.
However, at that point of the riddle, she still can't tell how old the man's children are. Therefore, she has to be stuck between multiple possibilities. To narrow it down further, only two sets of numbers that multiply to 72 share the same sum: (2,6,6) and (3,3,8).
After the man reveals that his oldest child likes chocolate pudding, however, the census taker can differentiate between the two options. That is, only the latter of those two sets has a distinct "oldest" child.

Nō. 12 You're in a dark room with a candle, a wood stove, and a gas lamp. You only have one match. What do you light first?

Nō. 13 There are five bags of gold that all look identical, and each has ten gold pieces in it. One of the five bags has fake gold in it. The real gold, fake gold, and all five bags are identical in every way, except the pieces of fake gold each weigh 1.1 grams, and the real gold pieces each weigh 1 gram. You have a perfectly accurate digital gram scale and can use it only once. How do you determine which bag has the fake gold?

Answer: Take one gold piece from the first bag, two from the second bag, three from the third bag, four from the fourth bag, and five from the fifth bag. If the weight on the scale ends in .1, then you know the first bag has the fake gold. If the weight on the scale ends in .2, then the second bag has the fake gold, and so on and so forth.

I'd like to state here that I got most of these riddles from Reddit so I won't be surprised if cheetah says it is similar to a post out there.
Hope you guys had a fun time solving it though.
