Question: Kimberly went hiking and took a 4-liter bottle full of water with her. The first time she drank from it, she consumed a quarter of the water in the bottle. Later on, she drank 2/3rd of the remaining water. How much water is left in the bottle (in liters)?
Answer: Her first drink consumed 1 / 4 * 4 = 1 liter of water. Thus there were 4 - 1 = 3 liters of water left in the bottle. Next, she drank 2 / 3 * 3 = 2 liters. Thus, there were 3 - 2 = 1 liters remaining. The answer is 1.

Question: Diana earned $150 in July. She earned 3 times this amount in August. In September, She earned twice the money she earned in August. How much money did Diana earn over these three months?

Question: There are one hundred tickets to be sold for a volleyball game. Andrea sold twice as many tickets as Jude while Sandra sold 4 more than half the number of tickets Jude sold. If Jude sold 16 tickets, how many tickets need to be sold?
Answer: Andrea sold 16 x 2 = 32 tickets. Half the number of tickets Jude sold is 16 / 2 = 8. So, Sandra sold 8 + 4 = 12 tickets. Thus, Andrea, Jude, and Sandra sold a total of 32 + 16 + 12 = 60 tickets. Therefore, 100 - 60 = 40 tickets need to be sold. The answer is 40.
