(A) To draw a histogram for a frequency distribution with unequal class intervals,we calculate the adjusted frequency for each class.$1$. Identify the minimum class width among all intervals:- Widths are: $(10-5)=5$,$(15-10)=5$,$(25-15)=10$,$(45-25)=20$,$(75-45)=30$.- The minimum class width is $5$.$2$. The formula for adjusted frequency is:$	ext{Adjusted Frequency} = \frac{	ext{Frequency of the class}}{	ext{Class width}} 	imes 	ext{Minimum class width}$.$3$. For the class $25-45$:- Frequency = $8$.- Class width = $45 - 25 = 20$.- Minimum class width = $5$.$4$. Calculation:$	ext{Adjusted Frequency} = \frac{8}{20} 	imes 5 = \frac{8}{4} = 2$.

Class interval	$5-10$	$10-15$	$15-25$	$25-45$	$45-75$
Frequency	$6$	$12$	$10$	$8$	$15$

Class	$0-5$	$5-10$	$10-20$	$20-30$	$30-50$	$50-70$	$70-100$
Frequency	$6$	$8$	$14$	$16$	$24$	$20$	$30$

Marks	$100-150$	$150-200$	$200-300$	$300-500$	$500-800$
Number of students	$60$	$100$	$100$	$80$	$180$

Head	Expenditure (in $Rs$)
Food	$4000$
Education	$2500$
Clothing	$1000$
House Rent	$3500$
