Question

Data of a survey is given below,for each type of food calculate the fraction of the total that the data represents,multiply each fraction by $360$ .Enter the value in the appropriate column.

Type of food	Number of Calories	Fraction of total	Degree of Sector
Home cooking	$1400$
Fast food	$400$
Junk food	$200$

Accepted Answer

The table is given as,

Type of food Number of Calories Fraction of total Degree of Sector

Home cooking $1400$

Fast food $400$

Junk food $200$

From the given table,we can calculate,
Total number of calories $= 2000$
Thus,
Fractional part of Home cooking food $= \frac{N u m b e r o f c a l o r i e s h o m e c o o k i n g f o o d}{T o t a l n u m b e r o f c a l o r i e s} = \frac{1400}{2000} = \frac{14}{20} = \frac{7}{10}$
Similarly,
Fractional part of fast food $= \frac{400}{2000} = \frac{4}{20} = \frac{1}{5}$

Fractional part of junk food $= \frac{200}{2000} = \frac{2}{20} = \frac{1}{10}$
Hence,on putting these values in table,
Required table is

Type of food Number of Calories Fraction of total Degree of Sector

Home cooking $1400$ $\frac{7}{10}$ $\frac{7}{10} \times 360 = 252$

Fast food $400$ $\frac{1}{5}$ $\frac{1}{5} \times 360 = 72$

Junk food $200$ $\frac{1}{10}$ $\frac{1}{10} \times 360 = 36$

Marks	$0$ greater than $0$	$10$ greater than $10$	$20$ greater than $20$	$30$ greater than $30$	$40$ greater than $40$	$50$ greater than $50$
Number of competitors	$40$	$36$	$22$	$11$	$2$	$0$

Class-Interval	$5 - 10$	$10 - 15$	$15 - 20$	$20 - 25$	$25 - 30$	$30 - 35$	$35 - 40$	$40 - 45$
Frequency	$5$	$6$	$15$	$10$	$5$	$4$	$3$	$2$
