[Question]A pen is longer than the rubber by 3 centimeters, and shorter than the pencil by 2 centimeters. Considering the pencil is 12 centimeters long, what is the total length of the rubber, the pen, and the pencil altogether?
[Answer]The pen is shorter than the pencil by 2 centimeters, so it's 12 - 2 = 10 centimeters long. That means the rubber is 10 - 3 = 7 centimeters long. So all accessories are 7 + 10 + 12 = 29 centimeters long altogether. The answer is 29.

[Question]Every week of last month Paul tried out a new cake recipe. The first week, he followed a cake recipe that called for 24 cups of sugar. Each week after that, he reduced the amount of sugar by half. How much sugar did he use for the cake on the fourth week?
[Answer]On the 2nd week, Paul halved the first week's sugar, therefore he used 24 / 2 = 12 cups. The third week, Paul used 12 / 2 = 6 cups. The fourth week, he used 6 / 2 = 3 cups. The answer is 3.

[Question]Last night, Olive charged her phone for 10 hours. Assuming each hour of charge lasts the phone 2 hours of use, calculate the total time Olive would be able to use her phone before it goes off if she charges it for 3/5 of the time she charged the phone last night.
[Answer]
If Olive charges her phone for 3 / 5 of the time she charged the phone last night, the phone would be charged for 3 / 5 * 10 = 6 hours. Assuming each hour of charge lasts the phone 2 hours of use, the phone will last for 6 * 2 = 12 hours before it goes off when Olive uses it on a six hours charge. The answer is 12.
