In a Mathematics test, the following marks were obtained by 40 students. Arrange these marks in a table using tally marks.

The following table represent marks obtained by 100 students in a test. Find mean marks of the students.

Following data gives the marks obtained by 100 students in a test. Find the median

The marks (maximum marks 100) obtained by 20 students in a test are given below : Find the mean marks of the 20 students.

The average marks of 39 students of a class is 50. The marks obtained by 40th student are 39 more than the average marks of all the 40 student are 39 more than the average marks of all the 40 students. Find the mean marks of all the 40 students.

In a class of 15 students, the total marks obtained by all the students in a test is 600. Find the average mark of the class.

The table shows the marks obtained by 25 students in a class test. Find the mean of the marks obtained

In an examination, student gets on average 76 marks. The total marks for five subjects is 500. His marks in 4 subjects are mentioned, calculate the marks obtained by the student in Mathematics marked as "x" in the table below. A. 80 B. 83 C. 72 D. 75

If for some x in R , the frequency distribution of the marks obtained by 20 students in a test is: Then the mean of the marks is:

The pie chart gives the marks scored in an examination by a student in different subjects. If the total marks obtained were 540, answer the following questions How many more marks were obtained by the student in Mathematics than in Hindi?
