This is the answer of your question

Answer 2

Answer:

So first we will draw four new columns naming $x_{i}$, $f_{i}$, $f_{i}$.$x_{i}$

and put values in column $x_{i}$ and $f_{i}$ as follows:-

C.I                        $x_{i}$                $f_{i}$        $f_{i}$.$x_{i}$

1000-1500         1250           24        30000

1500-2000        1750            10         17500

2000-2500       2250           33        74250

2500-3000        2750           28        77000

3000-3500        3250           30         97500

3500-4000        3750            22        82500

4000-4500        4250            16         68000

4500-5000        4750              7         33250

                                         ∑$f_{i}$=170          ∑$f_{i}$.$x_{i}$= 480000

Mean = ∑$f_{i}$.$x_{i}$ /∑$f_{i}$ =480000/170 =2823.529Rs

HOPE IT HELPS YOU!!!

HAVE A GREAT DAY AHEAD!! :-)
