The following table shows the distribution of some families according to expenditure per week .the number of families for two class intervalsare missing. Median =Rs.25 , Mode = Rs.24. calculate the missing frequency and hence the find mean.
| 0 - 10 | 10 -20 | 20 - 30 | 30 - 40 | 40 -50 |
| 14 | x | 27 | y | 15 |
The provided question is incomplete.
For finding the values of x and y, it is required either to give the total number of families or to provide the relation between x, y and the highest frequency (i.e., whether x > y > 27 and so on).
