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).
