Question

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

(a) Find how many students obtained marks equal to or more than 7.
(b) How many students obtained marks below 4?

Answer 1

By observing the marks scored by 40 students in the test, we can construct the table as follows.

(a) The students who obtained their marks equal to or more than 7 are the students who obtained their marks as either of 7, 8, and 9. Hence, number of these students = 5 + 4 + 3 = 12
(b) The students who obtained their marks below 4 are the students who obtained their marks as either of 1, 2, and 3.
Hence, number of these students = 2 + 3 + 3 = 8
