A girl has stolen two bars of solid gold, each weighing 20 pounds, and is running from some police. On the path she is on, she comes up to a rope bridge with a sign saying that the rope bridge can hold a maximum weight of 130 pounds, and that if any more weight is placed on the bridge it will collapse.

The girl knows her weight is 100 pounds, so she walks across the bridge carrying both gold bars(she doesn't throw them one by one in the air to across the bridge), and the bridge does not break.

How is this possible?

The gold bars were measured in Troy pounds, she would still be about 3 lbs over the limit. 1 Troy pound = .823 Avoirdupois pounds.

Spoiler for unless:

the girl is also made of gold.

Her weight of 100lb includes the 40lb of gold bars she is carrying, and if she dropped the bars she would only weigh 60lb.

Either that or she just takes a punt on the sign being a lie.

Wasn't this done with apples like a week ago?

[Guest]

What we do know is that she carries both bars across the bridge. What was not stated is, did she carry both bars together or separately. I say she took two trips.

[Guest]

1. 2 bridges. she took a different one

2. not on earth

a pound of gold is only 12oz. where a pound of anything else is 16 oz. Meaning 4 oz time 20 is 80 oz per bar of gold. 80 divided by 16 is 5. multiply 5lbs by 2 bars of gold and you get ten pounds. which puts the girl and the gold at 130 lbs.

There are only 12 ounces in a Troy pound of gold, but a Troy pound is still .823 times that of a "standard" pound. So, the girl weighing 100 "standard pounds" plus two 20 Troy pound bars of gold would weigh about 133 "standard" pounds.

Excellent answer, Prof!

However, if you want to go WAY outside of the box...

She took two lines of the rope bridge and braided them, making them stronger, then tightrope walked her way across. All this while the police were playing on their calculators figuring out Troy vs. Avoirdupois weight!

The professor is exactly right - except that the girl's name is 'Jewel', and she is so pretentious that she measures her own weight in Troy pounds. Since the bridge is not a precious metal or gem, it's weight limit (she hopes) is in Avoirdupois pounds. Converting the weight of her body and the gold, exactly 140 (Troy) lbs since she was scantily clad, we get:

140 x 0.823 = 115.22 Avoirdupois pounds!

~ or ~

She tied the bars of gold to a rope, and dangled them in the water below. Since the bars displace water, they weighed enough less that she was able to scramble across safely. However, the portly police officers who tried to chase her broke the bridge and fell, allowing her to escape completely.

Who says that crime doesn't pay!

she walks across kind of juggling them so that she is only holding one at a time.

I've heard this one before, but it was different

Yes, it was done with apples, like I said. Only problem being I imagine it would be slightly more difficult to juggle bars of gold than apples.

she cuts off her arm

Since the bars of gold weigh 20 pounds each, the girl could have found a way to cut one of them in half.That would make the bar only ten pounds and since 100+20+10=130 it would work out
