Test: Tables - 1 - Question 6

Directions : Read the following table chart carefully and answer the questions given beside.
The following table shows the number of students in classes 8, 9 and 10 in a school. The school started in 2000 and students are admitted only in class 8. At the end of the year the students who pass the final exams get promoted to the next class while the students who fail stay in the same class and are joined by a new bunch of students, who are either promoted (class 9 and 10) or who joined the school new (class 8). All students who pass the class 10 exams pass out of the school.

No student in class 10 failed in any of the years and no student failed in the same class more than once.

Q. How many students joined the school from 2000 to 2004?

Detailed Solution for Test: Tables - 1 - Question 6

Following the common explanation, we get
The number of students who joined the school = 45 + 47 + 42 + 47 + 45 = 226
Hence, option C is correct.

Common explanation :
As it is given that a student who passes the final exams gets promoted to the next class, we can see that only 42 of the 45 students in class 8 in the year 2000, reached class 9, which means that 3 students had failed in the class that year. As the number of students in class 8 in 2001 is 50, 47 new students (50-3 failed students) joined class 8 in that year. In 2002, 36 students passed out of class 10, which means of the 42 students in class 9 in 2001, only 36 passed and 6 failed. This six students will remain in class 9 in 2002 also and as these are 52 students in class 9 in that year, 46 students were newly promoted, i.e, of the 50 students in class 8 in 2001.
Similarly we can find values for other years.

Following the common explanation, we get
Of the 46 students in class 9 in 2003, only 43 got promoted to class 10,i.e., 3 students failed.
Hence, option B is correct.
Common explanation :
As it is given that a student who passes the final exams gets promoted to the next class, we can see that only 42 of the 45 students in class 8 in the year 2000, reached class 9, which means that 3 students had failed in the class that year.
