Randy has two drinking glasses with circular bases. The first glass is twice as tall as the second glass, and the second glass has a base with twice the radius of the first glass. Which glass holds more water?
The second glass. Doubling the radius of the base doubles the glass's size in two dimensions (depth and width) while doubling the height doubles the glass's size in only one dimension (height). In fact, the second glass will have twice the volume of the first glas.s

What relationship do the following people have to you? 1) Your only uncle's only brother's only child. 2) Your mother's sister's daughter's only cousin 3) Your maternal grandmother's son's only brother-in-law's child.
In all three cases, the person described is you yourself. Note that the word "only" makes all the difference. In the first instance, for example, you can't cite your cousin as a valid anser, because under the parameters of the question, you have only one uncle, who has only one brother (your father), and your father has only one child (you).

Four retired friends meet in the park each day to play chess. The mode of their ages is 58. The median of their ages is 62. Ronald, the most senior member of the group, turned 70 on his last birthday. What is the mean of their ages?
The mean is 63. The mode is 58 and the median is 62, so the youngest two are 58. The second oldest must be 66, because 62 is half way between 58 and 66. The friends are 58, 58, 66, and 70, which totals to 252, and 252/4=63.
