Question: A car is driving through a tunnel with many turns. After a while, the car must travel through a ring that requires a total of 4 right-hand turns. After the 1st turn, it travels 5 meters. After the 2nd turn, it travels 8 meters. After the 3rd turn, it travels a little further and at the 4th turn, it immediately exits the tunnel. If the car has driven a total of 23 meters around the ring, how far did it have to travel after the 3rd turn?
Answer: From the details given, the car has traveled 5 meters at the 1st turn + 8 meters after the 2nd turn + 0 meters after the 4th turn = 13 meters around the ring. It must therefore have driven 23 total meters – 13 calculated meters = 10 meters after the 3rd turn. The answer is 10.

Q: A gallon of whole milk that normally costs $3 is now sold at $2. A box of cereal was sold at a discount of $1. How much will you save via discounts if you buy 3 gallons of whole milk and 5 boxes of cereal?
A: The discount for each gallon of whole milk is $3 - $2 = $1. So the discount for 3 gallons of whole milk is $1 / gallon x 3 gallons = $3. The total discount for 5 boxes of cereal is $1 / box x 5 boxes = $5. You will save $3 + $5 = $8 for 3 gallons of whole milk and 5 boxes of cereal. The answer is 8.
Question: Omi is twice as old as Kimiko. Arlette is 3/4 times as old as Kimiko. If Kimiko is 28 years old, calculate the average age of the three?
Answer: If Kimiko is 28, Omi is 2 * 28 years = 56 years old. Arlette is 3 / 4 * 28 years = 21 years old. If you add up their ages, it sums to 21 years + 56 years + 28 years = 105 years. The average age for the three is 105 years / 3 people = 35 years / person. The answer is 35.
[Question]Perry, Dana, Charlie, and Phil played golf together every week. At the end of the season, Perry had won five more games than Dana, but Charlie had won 2 games fewer than Dana. Phil had won 3 games more than Charlie did. If Phil won a total of 12 games, how many more games did Perry win than did Phil?
[Answer]If Phil had won 3 games more than did Charlie, and Phil won 12 games, then Charlie won 12 - 3 = 9 games. If Charlie had won 2 games fewer than Dana, and Charlie won 9 games, then Dana won 9 + 2 = 11 games. If Perry had won five more games than did Dana, and Dana won 11 games, then Perry won 11 + 5 = 16 games. Thus, Perry won 16 - 12 = 4 more games than did Phil. The answer is 4.
[Question]5,000 people live in a small town. 2,000 males live in that town and the rest of the population are females. Thirty percent of the female population wears glasses. How many females wear glasses?
[Answer]
There are 5,000 - 2,000 = 3,000 females that lives in the town. Since thirty percent of the female population wears glasses, 30 / 100 * 3,000 = 900 females wear glasses. The answer is 900.
