From the table, check how many times she receives the cashback worth of rupees 40 to 60 and then compare this value with the total number of times she receives the cashback.

We have to find cashback of 40 to 60 rupees.

Using upper limits and lower limits 40 comes upto 40-60 class. and 60 belong to 60-80 class.

By using this I can't get it 17 as Answer.

Let me know where I am wrong?? Please any one guide me

Hi,

The answer to the second question is correct as explained in the above mail.

For the first question, we need to just find out percentage relative freqency corresponding to class 40-60.

The frequency of cashback she recieved for 40-60 slab is 6. The total frequency of cashback she recieved is 5+10+6+8+6 =35.

The percentage relative frequency is 6/35 *100 = 17.14
