Answer 2

Rs. 1500 / week

In this number of families is our frequency. We will find total and cumulative frequencies.

here, CF = 500 = N

Hence N/2 = 500/2 = 250

Our median class will be nearly 250 value i.e., 1000-2000.

h = 1000 ( difference in expenditure amount i.e., 2000-1000 or 3000-2000)

By using Median Formula i.e., = l + {(N/2 - CF)/f} *h

                                                  = 1000 + {(250 - 150)/200} * 1000

                                                  = 1500

Hence, the median expenditure is Rs. 1500 per week.
