Q: The first tank is 300 liters filled while the second tank is 450 liters filled. The second tank is only 45% filled. If the two tanks have the same capacity, how many more liters of water are needed to fill the two tanks?
A: Since 450 liters represents 45%, then each 1% is equal to 450 liters / 45 = 10 liters. Hence, the capacity of each tank is 10 liters x 100 = 1000 liters. So, the first tank needs 1000 - 300 = 700 liters of water more. While the second tank needs 1000 - 450 = 550 liters more. Therefore, 700 + 550 = 1250 liters of water are needed to fill the two tanks. The answer is 1250.
Question: In a building, there are a hundred ladies on the first-floor studying. There are three times that many girls at a party being held on the second floor of the building. How many ladies are on the two floors in total?
Answer: If there are a hundred ladies in the living room and three times that many girls at the party, there are 3 * 100 = 300 girls at the party. In the building there are 100 + 300 = 400 ladies. The answer is 400.

Q: Taipei 101 in Taiwan is 1,673 feet tall with 101 floors. Suppose the first to 100th floors have height each equal to 16.5 feet, how high is the 101st floor?
A: The total height of the first to 100th floor is 100 x 16.5 = 1650 feet. Hence, the 101st floor is 1673 - 1650 = 23 feet high. The answer is 23.
Question: Cody goes to the store and buys $40 worth of stuff. The taxes were 5%. After taxes, he got an $8 discount. Cody and his friend split the final price equally. How much did Cody pay?
Answer: The taxes were 40 * .05 = $2. So the price was 40 + 2 = $42. He got a discount so the price he paid was 42 - 8 = $34. Since he paid half his price was 34 / 2 = $17. The answer is 17.
Q: 10 boxes each contain 50 bottles of water. Each bottle has a capacity of 12 liters and is filled up to 3/4 of its capacity. How many liters of water altogether are contained within the bottles in the boxes?
A:
Since each water bottle has a capacity of 12 liters, when filled up to 3 / 4 of capacity, each carries 3 / 4 * 12 = 9 liters of water. If there are 50 bottles of water in each box, the number of liters the water bottles in a box are carrying is 50 * 9 = 450 liters. In 10 boxes containing bottled water, the total number of liters in the water bottles is 450 * 10 = 4500 liters. The answer is 4500.
