Bob has a cube of silver that measures 3 inches on each side. A cubic inch of silver weighs 6 ounces. Each ounce of silver sells for $25. He sells it for 110% of its silver value. How much does he sell it for?
Let's think: The silver has a volume of 3 * 3 * 3 = 27 cubic inches. So it weighs 27 * 6 = 162 ounces. So its value is 162 * 25 = $4050. That means he sold it for 4050 * 1.1 = $4455.. The answer is: 4455.

John has 25 horses. He feeds each horse twice a day and feeds them 20 pounds of food at each feeding. He buys half ton bags of food. How many of those will he have to buy in 60 days?
Let's think: He feeds each horse 2 * 20 = 40 pounds of food a day. So he uses 40 * 25 = 1000 pounds of food a day. That means in 60 days he uses 60 * 1000 = 60000 pounds of food. Each bag of food is 2000 * .5 = 1000 pounds. So he needs to buy 60000 / 1000 = 60 bags of food.. The answer is: 60.

John is working as an IT specialist. He repairs broken computers. One day he had to fix 20 computers. 20% of them were unfixable, and 40% of them needed to wait a few days for spare parts to come. The rest John was able to fix right away. How many computers John was able to fix right away?
Let's think: From all the computers, 100% - 40% - 20% = 40% got fixed right away. So John was able to fix 40 / 100 * 20 = 8 computers.. The answer is: 8.

A house's living room, dining room and kitchen take up 1,000 sq ft. The house also has a guest bedroom and a master bedroom suite. If the guest bedroom is a quarter of the size of the master bedroom suite, and the house is 2,300 sq ft total, how large is the master bedroom suite?
Let's think:
The house is 2,300 sq ft and we know the non - bedroom sections take up 1,000 sq ft, so that leaves 2300 - 1000 = 1,300 sq ft for the bedrooms / bathrooms. Let x be the size of the master bedroom suite. Then the guest bedroom is 0.25x. So together the bedrooms are x + 0.25x = 1.25x in size. This means 1.25x = 1300. So x = 1300 / 1.25 = 1040 sq ft.. The answer is: 1040.
