**The runs scored by two teams A and B on the first 60 balls in a cricket match are given below:**

Represent the data of both the teams on the same graph by frequency polygons.

[**Hint:** First make the class intervals continuous.]

**Solution:**

We can note that the class intervals are not continuous. So, we will make them continuous.

Lower limit of any random class - Upper limit of previous class = 7-6 = 1 and half of 1 is equal to 0.5.

So, we will subtract 0.5 from all the lower limits and will add 0.5 to all the upper limits. Doing so, we will have continuous class intervals:

We can find class marks for both of the teams. Class intervals are same for both the teams which means that class marks will also be same for both the teams.

**Class mark =(lower limit + upper limit)/2**

Now, we can draw frequency polygons for both the teams.
