<em>Note:</em> <em>As you missed to identify what we have to find in this question. But, after a little research, I am able to find that we had to find the Mode for the data given in your question. So, I am assuming we have to calculate the the Mode. Hopefully, it would clear your concept regarding this topic.</em>
Answer:
The mode of the data = 75
Step-by-step explanation:
Lets visualize the given data in a table to show the frequency distribution:
<em>Daily expenditure on milk (in Rs) Number of households</em>
<em> 0-30 5</em>
<em> 30-60 6 </em>
<em> 60-90 9</em>
<em> 90-120 6</em>
<em> 120-150 4</em>
Here the maximum frequency is 9.
So, modal class is <em>60-90.</em>
<em />
As the formula to calculate the mode:
Here, the maximum
is the lower limit of the class
is the frequency of the modal class
is the frequency of the previous modal class
is the frequency of the next previous modal class
is the class size
So,
∴ The mode of the data = 75
