The following pie chart shows the marks obtained by a student in an examination, who scored 720 marks in all. Study the diagram and answer the questions given below.
The marks scored in Mathematics and English together differ from the total marks scored in Bengali, History and Science by
The marks scored in Mathematics = $$\frac{90}{360}\times720$$ = 180
The marks scored in English = $$\frac{60}{360}\times720$$ = 120
The marks scored in Bengali = $$\frac{70}{360}\times720$$ = 140
The marks scored in History = $$\frac{65}{360}\times720$$ = 130
The marks scored in Science = $$\frac{75}{360}\times720$$ = 150
The marks scored in Mathematics and English together = 180+120 = 300
The marks scored in Bengali, History and Science together = 140+130+150 = 420
difference = 420 - 300 = 120
so the answer is option C.
