Question

the annual profit earned by 30 shops in lpcality gives the rise to the following​

Answer 1

Step-by-step explanation:

For more than method:

Now, we mark on x-axis lower class limits, y-axis cumulative frequency

Thus, we plot the points (5,30),(10,28),(15,16),(20,14),(25,10),(30,7)and(35,3)

Less than method:

Profit in lakhs No. of shops Profit less than C.F

0−10 2 10 2

10−15 12 15 14

15−20 2 20 16

20−25 4 25 20

25−30 3 30 23

30−35 4 35 27

35−40 3 40 30

Now we mark the upper class limits along x-axis and cumulative frequency along y-axis.

Thus we plot the points (10,2),(15,14),(20,16),(25,20),(30,23),(35,27),(40,30)

We find that the two types of curves intersect of P from point L it is drawn on x-axis

The value of a profit corresponding to M is 17.5. Hence median is 17.5lakh
