6.     Manisha has rupees notes of different denominations. She noted down the number of notes of various denominations
                   in a table as follows. Calculate the mode of the given data.

                              Rupee Denomination         10      20      50      100     500      2000

                              No. of notes               40      50      20      25       15       1

              Ans.  Mode is the value which occurs the most in a list. From the above data, we can see that the 20 rupees note has the
                   highest number. So, the mode is 20.

              7.   Find the median of the following vales:

                   12, 110, 18, 12, 15, 19, 13, 12, 110, 115, 17

              Ans.  Arranging the data in ascending order:
                   12     12     12     13     15     17     18     19     110     110     115
                                 th
                   Median =   n+1    item   n=11
                              2

                   So,   11+1  =6  item = 17.   Median = 17
                              th
                         2
              8.   Create a frequency table for the following:
                   12       5     4     3    8      9    12        9      8      7
