Question: A question and answer forum has 200 members. The average number of answers posted by each member on the forum is three times as many as the number of questions asked. If each user posts an average of 3 questions per hour, calculate the total number of questions and answers posted on the forum by its users in a day.
Answer: If each user posts an average of 3 questions per hour, the average number of answers posted on the forum is 3 times the number of questions which totals to 3 * 3 = 9 answers per. hour. In a day, with 24 hours, the average number of questions asked by each member is 24 * 3 = 72,. If there are 200 users of the forum, the total number of questions asked is 200 * 72 = 14400 questions in a day. At the same time, a member posts an average of 9 * 24 = 216 answers in a day. Since there are 200 members who use the forum, the total number of answers posted in the forum in a day is 200 * 216 = 43200. In total, the number of questions and answers posted on the forum is 43200 + 14400 = 57600. The answer is 57600.

Question: Tom Sawyer has tricked his friends into whitewashing Aunt Polly's 100-foot fence. His first friend, Ben, whitewashed 10 feet. His second friend Billy whitewashed a fifth of the remaining fence. A third friend, Johnny, whitewashed a third of the fence that was left after that. How much of the fence still needs to be whitewashed?
Answer: It's a 100 - foot fence, and Ben whitewashed 10 feet, so there are 100 - 10 = 90 feet left after Ben is done. Billy whitewashed a fifth of that, or 90 / 5 = 18 feet. There is now 90 - 18 = 72 feet of fence left. Johnny whitewashes a third of that, or 72 / 3 = 24 feet. That leaves 72 - 24 = 48 feet of fence left to be whitewashed. The answer is 48.

Question: Sarah bought 12 lollipops filled with caramel for a total of 3 dollars. She offered to share one-quarter of the lollipops with her friend, Julie, but Julie insisted on reimbursing Sarah for the cost of the lollipops shared. How much money, in cents, did Julie give Sarah to pay for the shared lollipops?
Answer:
Since one dollar is 100 cents, then 3 dollars is 3 * 100 = 300 cents. The cost for one lollipop is 300 / 12 = 25 cents. One - quarter of the lollipops is 12 / 4 = 3 lollipops. At 25 cents per lollypop, 3 lolly’s cost 3 * 25 = 75 cents. The answer is 75.
