Question: Rajesh walked 10 kilometers less than 4 times the distance that Hiro walked. Together they walked 25 kilometers. How many kilometers did Rajesh walk?
Answer: Let H = distance Hiro walked. 4H - 10 = distance Rajesh walked. H + 4H - 10 = 25. 5H - 10 = 25. 5H = 35. Hiro walked 7 km so Rajesh walked 4(7) - 10 = 18 km. Rajesh walked 18 kilometers. The answer is 18.

Question: William is a jockey. He can ride his horse for 6 hours a day. Over 6 days, he only used the maximum riding time twice. On two days he rode his horse for only 1.5 hours a day and half the maximum time for the next two days. How many hours did William ride his horse during those 6 days?
Answer: William used two days to the limit, which means 6 * 2 = 12 hours of horse riding. For two days he rode a horse 1.5 a day, which makes up to 1.5 * 2 = 3 hours. For the next two days, he used only half of the maximum time which means 6 * 0.5 = 3 hours a day. That means 2 * 3 = 6 hours during these two days. So in total William rode his horse for 12 + 3 + 6 = 21 hours. The answer is 21.

Question: Pearl wants to order 5 monogrammed Christmas stockings for each of her 5 grandchildren and her own 4 children. The stockings are $20.00 each and currently 10% off. The monogramming will costs $5.00 per stocking. How much will the stockings costs?
Answer: She has 5 grandchildren 4 children so she needs 5 + 4 = 9 stockings. The stockings are $20.00 each and currently 10% off so that's 20 * .10 = $2.00 off. The stockings are $20.00 with a $2.00 discount so they are each 20 - 2 = $18.00. The stockings are now $18.00 and she needs 9 so that's $162.00. She also wants to monogram each stocking at $5.00 per stocking so that's 9 * 5 = $45.00. The stockings are $162.00 and the monogramming will cost $45.00 so the stockings will cost 162 + 45 = $207.00. The answer is 1035.

Question: There are enough provisions in a castle to feed 300 people for 90 days. After 30 days, 100 people leave the castle. How many more days are left until all the food runs out?
Answer:
After 30 days, there will be enough food left to sustain 300 people for 90 days – 30 days = 60 days. After the 100 people leave, there will be 300 - 100 = 200 people left. The 200 people will eat 200 / 300 = 2 / 3 as much food as the original group of people in the castle. The 60 days' worth of food will last this smaller group for 60 days / (2 / 3) = 90 more days. The answer is 90.
