The following table shows the marks (in percentages) obtained by six students in four different subjects in an examination. The maximum marks in each subject is 100.
Answer the following questions based on the table: In which of the following subjects is the average of the percentage marks obtained by the six students the highest? |
Maths Geography Chemistry Physics |
Geography |
Average of percentage marks of Physics = \(\frac{85 + 75 + 80 + 90 + 95 + 90 }{6}\) = \(\frac{434 }{6}\) = 72.33 Average of percentage marks of Chemistry = \(\frac{90 + 75 + 60 + 85 + 90 + 90 }{6}\) = \(\frac{ 490 }{6}\) = 81.67 Average of percentage marks of Maths = \(\frac{70 + 75 + 75 + 75 + 85 + 95 }{6}\) = \(\frac{475 }{6}\) = 79.167 Average of percentage marks of Geography = \(\frac{80 + 85 + 85 + 90 + 90 + 90 }{6}\) = \(\frac{ 520}{6}\) = 86.67 So , Average is highest for Geography. |
