According to given bar graph , we have
Total marks obtained in Biology for two terms = 85 + 60 = 145
Total marks obtained in English and Mathematics for first term = 70 + 100 = 170
Required ratio = average of the marks obtained in Biology for two terms : average of the marks obtained in English and Mathematics for first term
| Required ratio = | = | = 145 : 170 = 29 : 34 | 2 | 2 |
