Consider the following frequency distribution table. Class interval 10-20 20-30 30-40 40-50 50-60 60-70 70-80 Frequency 180 $f_1$ 34 180 136 $f_2$ 50
If the total frequency is 685 & median is 42.6 then the values of $f_1$ and $f_2$ are
| Class interval | 10-20 | 20-30 | 30-40 | 40-50 | 50-60 | 60-70 | 70-80 |
| Frequency | 180 | $f_1$ | 34 | 180 | 136 | $f_2$ | 50 |
