Ancient Coin Puzzle | 14 Oct 2009

Thief once got hold of coin which read 250 B.C. so he understood it is an ancient coin and wanted a great price for it and one day he read something that lit his eyes. He saw "We buy BC coins at the rate of 100 \$ per year old starting at \$10,000 for the first year".

How much money can the thief expect.

He can expect \$0 and a pair of handcuffs - no coin would ever have a BC date on it! So the advert would have been posted by police looking for dumb criminals.

Every coin here in India have a manufacturing date on it.

Re: Ancient Coin Puzzle | 14 Oct 2009

I guess it's this way :
Net amount (expected) = \$10,000 + (\$100 *248) = \$10,000 + \$24,800 = \$34,800
\$10,000 for first year and \$100 for each of the rest 248 years. :thinking:

I knew that wasn't the answer that shabbir was looking for :D

Since the current year is 2009AD and the coin dates back to 250BC.
So the difference in yrs is 2009-(-250) = 2259
And the prize is only for old coins so current year would not yield any money
2259-1=2258
and \$100/year and \$10,000 for first year so... 2257*100+10000 = 235700

hmm, even sp's got the point, that the deals only for BC coins, so 2009 yrs does not make any money :(

1. He is said to be a thief in the first place.

2. A coin that old must be handed over to archies. If he holds it, he is a double thief then.

Arrest him immediately.

249*100+10,000

SP how 248 years.

1 BC would be \$10k
2 BC would be \$10k+\$100
