95. A man has 3 daughters. The oldest daughter is 3 years older than the middle daughter and the middle daughter is 3 years older than the youngest daughter. Together, the daughter's ages add up to 57. How old are the girls?
The daughter's ages are 16, 19 and 22. If you consider the youngest girl to be x, then the middle girl is x + 3, and the oldest is x + 6. Together, they are 57; so x + x +3 + x + 6 = 57, then 3x + 9 = 57, 3x = 48 and then x = 16.
96. A group of sheep and chickens have a total of 99 heads and feet. There are twice as many chickens as sheep. How many of each are there?
Let S be the number of sheep and C be the number of chickens. So: 2S = C and also 5S + 3C = 99. Now, multiply each side of the first equation by 3 and then solve for 0 gives: 6S - 3C = 0. Then we can add this to the second equation, which yields: 11S = 99. By solving for S, we find that S equals 9. By substituting back in one of the original equations, we find that C equals 18. So there are nine sheep and eighteen chickens.
97. What's not a game, but can be played; is never seen, but often made.
98. On a shelf in the library, there is a 3 book set of almanacs labeled volume 1, volume 2 and volume 3. Each book is 2 1/2 inches thick, the pages being 2 inches thick and each cover is 1/4 inch thick. A bookworm starts eating it's way from the 1st page of volume 1 and stops at the last page of volume 3. How far did the bookworm travel?
3 inches. When the books are on the shelf with their binders facing you, the right side of volume 1 is where page 1 is and the left side of volume 3 is the last page of volume 3. This being the case, the worm only eats through the cover of volume 1 ( 1/4 inch ), all of volume 2 ( 2 1/2 inches ), and only the cover of volume 3 ( 1/4 inch ) for a total of 3 inches.

100. Joe makes and sells birdhouses at an antique market for $50 each. It takes him forty-five minutes to make a birdhouse and his only costs are for materials. He sold 100 last year, for a profit of $2,000. This year he raises the price by 20%, but sells 30% fewer birdhouses. If the cost for making each birdhouse remains the same, does he make a bigger or smaller profit this year and by what percentage?
5%. Last year, his profit on 100 birdhouses was $2,000, or $20 per birdhouse; so we can calculate that his cost is $30 for each birdhouse ($50 sales price - $20 profit). At the new price of $60 (20% more than $50) he makes $30 per table. Therefore, even though he only sells 70 tables (30% fewer than 100), he makes $2,100 - 5% more than last year.
