The following pie-chart gives the marks scored in an examination by a student in various subjects. If the total marks obtained by the student were 540, answer the following questions.

The adjoining pie chart gives the marks scored in an examination by a student in Hindi, English, Mathematics, Social Science and Science. If the total marks obtained by the students were 540, answer the following questions.(i) In which subject did the student score 105 marks?(Hint: for 540 marks, the central angle = 360°. So, for 105 marks, what is the central angle?)(ii) How many more marks were obtained by the student in Mathematics than in Hindi?(iii) Examine whether the sum of the marks obtained in Social Science and Mathematics is more than that in Science and Hindi (Hint: Just study the central angles).

In an examination, a student requires 40% of the total marks to pass. If the student secures 185 marks and fails by 15 marks, find the total marks.

In Figure, the pie-chart shows the marks obtained by a student in various subjects. If the student scored 135 marks in mathematics, find the total marks in all the subject. Also, find his score in individual subjects.
