6.The following table gives the distribution of students according to the marks obtained in a paper: Marks Number of StudentsBelow 10 15Below 20 38Below 30 65Below 40 84Below 50 100What is the number of students getting 30 or more than 30 marks ?

The correct answer is (d).

The number of students getting 30 or more than 30 marks is 65 + 84 = 149. However, since the question asks for the number of students getting 30 or more than 30 marks, we need to subtract the number of students getting exactly 30 marks, which is 65. Therefore, the number of students getting 30 or more than 30 marks is 149 – 65 = 84.

Option (a) is incorrect because it is the number of students getting less than 30 marks.

Option (b) is incorrect because it is the number of students getting less than or equal to 30 marks.

Option (c) is incorrect because it is the number of students getting 30 marks or more.
