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 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
