Hint
Do leap years make a difference?
Answer
Hours in 10 years.
Reasoning
In a day, there are 60 x 60 x 24 seconds = 86,400 seconds.
In 10 years, there are 10 x 365 x 24 hours = 87,600 hours, which even without the leap years is already the larger number.

Hint
There are 1,760 yards in a mile, 3 feet in a yard, and 12 inches in a foot.
Answer
Inches in a mile.
Reasoning
There are 1,760 yards in a mile, 3 feet in a yard, and 12 inches in a foot.
There are 1760 x 3 x 12 = 63,360 inches in a mile, and around 1,000 x 52 = 52,000 Sundays in a thousand years.
Depending on the day of the week the first day of the year falls, there are either 52,177 or 52,178 Sundays in a thousand years.
Puzzle 95
Yesterday I was asked to buy some stamps.
Stamps, in the land of BrainBashers, are available in 2p, 7p, 10p, 15p and 20p denominations.
For three types of stamp, I was asked to buy five of each.
For the other two types of stamps, I was asked to buy six of each.
Unfortunately, I forgot which I was supposed to buy five of and which to buy six of.
I had been given £3.00, which just happened to be the exact money required, so the shopkeeper was able to work out what stamps I needed.
Which stamps did I buy?

Hint
I bought at least 5 of every stamp.
Answer
Five lots of 2p, 7p and 15p, and six lots of 10p, and 20p.
Reasoning
The shopkeeper rightly figured that I required five lots of all of the stamps, which came to (2p + 7p + 10p + 15p + 20p) x 5 = £2.70.
For two of the stamps I needed one more of each, and these must have added to the remaining 30p, so can only have been the 10p and 20p stamps.

My BrainBashers electronic world atlas has developed another fault.
I listed six countries, and how far away each was from England, and here are the results:
Spain 14,000 miles
Fiji 12,000 miles
Germany 18,000 miles
Brazil 16,000 miles
India 16,000 miles
Iceland --,--- miles
How far away did it list Iceland as?

Hint
Look at the vowels (AEIOU).
Answer
20,000.
Each vowel (AEIOU) is worth 4,000 miles and each consonant is worth 2,000.
