Average of 17 students in a class is X. When their marks are arranged ...
X < />
c)X > Y
d)The relationship between X and Y cannot be determined based on the given information
The answer is d) The relationship between X and Y cannot be determined based on the given information.
Explanation:
The average of the 17 students in the class is X. This means that the sum of their marks divided by 17 equals X.
When their marks are arranged in ascending order, it forms an arithmetic progression. This means that the difference between any two consecutive marks is the same.
The class teacher found that the students ranked 15th, 11th, 9th, and 7th had copied the exam and were suspended. This means that their marks were not valid and should not be included in the calculation of the average.
However, we do not have any information about the specific marks of these suspended students or the specific marks of the remaining students. We only know that their ranks were 15th, 11th, 9th, and 7th.
Therefore, we cannot determine the exact values of X and Y or their relationship without more information.
