A school has 10 classes with the same number of students in each class. One day, the weather was bad and many students were absent. 3 classes were half full, 5 class were 3/4 full and 2 classes were 1/6 empty. A total of 74 students were absent. What is the total number of students in this school?

Correct Answer: 240
Let x = number of students in each class. Then total number of students in school. is = 10x If 3 classes are half full then we have 3x/2 students absent. If 5 classes are 3/4 full that means that (1/4)*5x students are absent. If 2 classes are 1/6 empty that means that (1/6)*2x students are absent. Now we are told that (3x/2) + (1/4)*5x + (1/6)*2x = 74 or,(3x/2) + (5x/4) + (x/3) = 74 or,18x + 15x + 4x = 888 or,7x = 280 x = 24  number of students in each class is 24 number of student in this school = 10x                                 = 10*24 = 240 ans: 240

A pipe, working at full speed, can fill an empty cistern in 1 hour. However, during the first hour it worked at one-twelfth of its capacity, during the second hour at one-ninth of its capacity, during the third hour at one-sixth of its usual capacity and during the fifth hour it was only one -third as efficient as it was supposed to be. A second pipe also displayed similar performance, but if it worked at full speed would have filled the empty cistern in 2 hours. Together with a drain pipe that drained water out of the tank at a constant rate, the empty cistern could be filled in 5 hours, all the three pipes working concurrently. How many hours will it take the drain pipe to empty the filled cistern if no other pipe was functioning during the time?
