Which Coin is Counterfeit?

You are given eight coins and told that one of them is counterfeit. The counterfeit one is slightly heavier than the other seven. Otherwise, the coins look identical. Using a simple balance scale, how can you determine which coin is counterfeit using the scale only twice?

First weigh three coins against three others. If the weights are equal, weigh the remaining two against each other. The heavier one is the counterfeit. If one of the groups of three is heavier, weigh two of those coins against each other. If one is heavier, it’s the counterfeit. If they’re equal weight, the third coin is the counterfeit.

I Live in Water

I live in water
If you cut my head I’m at your door,
If you cut my tail I’m fruit,
If you cut both I’m with you

What am I?

A pearl. They’re found underwater. Removing the head (p) leaves Earl, a guy who could be at your door. Removing the tail (l) leaves pear, a fruit and if you cut both off you’re left with ear, which is with you because it’s attached to your head.

Not a Bird Though Feathered

It’s not a bird, though feathered, and
it has a mobile nest.
It’s quick in flight and, having flown,
it always stops to rest.

An arrow. It has feathers and its nest (a quiver) is usually carried an archer’s back. The arrow flies when released, but will always land somewhere to rest.

Three Brothers Share A Family Sport

Three brothers share a family sport:
A non-stop marathon
The oldest one is fat and short
And trudges slowly on
The middle brother’s tall and slim
And keeps a steady pace
The youngest runs just like the wind,
A-speeding through the race
“He’s young in years, we let him run,”
The other brothers say
“‘Cause though he’s surely number one,
He’s second, in a way.”

The hands on a clock (hour, minute, second).

Losing Ten Minutes An Hour

A clock loses exactly ten minutes every hour. If the clock is set correctly at noon, what is the correct time when the clock reads 3:00pm?

3:36pm. For every 60 minutes of real time, the clock moves 50 minutes. Put another way, 60/50 = 1.2 real minutes per slow-clock minute.

In order for the clock to show 3:00pm, 180 of its slow minutes have to pass. 1.2 * 180 clock minutes = 216 real minutes or 3 hours and 36 minutes.
