If there are 92 students and 20 students take the bus home, the number of students who haven't taken the bus is 92 - 20 = 72 students. 5 / 8 of the students who didn't take the bus home ride bikes home, a total of 5 / 8 * 72 = 45 students. The number of students who neither took the bus nor biked home but walked home is 72 - 45 = 27.
The answer: 27

From Monday to Thursday, the cobbler can mend 3 x 8 = 24 pairs of shoes a day. From Monday to Thursday, he can mend 24 x 4 = 96 pairs of shoes. On Friday, he works for 11 - 8 = 3 hours. On Friday, he can mend 3 x 3 = 9 pairs of shoes. In a week, he can mend 96 + 9 = 105 pairs of shoes.

Reasoning and answer: If the shadows lengthen by 5 feet per hour, this means that in 6 hours the shadows would have lengthened from zero to 5 * 6 = 30 feet. Since there are 12 inches in every foot, this means the building's shadow would be 30 * 12 = 360 inches in length.
The answer: 360
