Answer 2

Answer:

(a) number of students who like chocolate is 69

(b) number of students who  prefer pasta is 81

(c) angle of the sector representing ice cream is 72°

(d) angle of the sector representing pizza is 54°

(e) total number of students surveyed is 700

(f) total number of students surveyed is 600

(g) number of students whose favourite food is ice cream is 80

(h) number  of students whose favourite food is noodles is 72

Step-by-step explanation:

(a) total students surveyed = 300

 % of students who like chocolate = 23%

number of students who like chocolate = $\frac{23(300)}{100}$ = 69

(b)  total students surveyed = 450

% of students who prefer pasta = 18%

number of students who  prefer pasta = $\frac{18(450)}{100}$ = 81

(c) % of students who prefer ice cream = 20%

angle of the sector representing ice cream = $\frac{20(360)}{100}$ = 72°

(d)  % of students who prefer pizza = 15%

angle of the sector representing pizza = $\frac{15(360)}{100}$ = 54°

(e)  number of students whose favourite food is pasta = 126

and, %  of students whose favourite food is pasta = 18%

$126 = \frac{18. total \ number \ of \ students}{100}$

total number of students surveyed = $\frac{126(100)}{18}$ = 700

(f) given, number of students whose favourite food is noodles = 144

% of students whose favourite food is noodles  = 24%

$144 = \frac{24. total \ number \ of \ students}{100}$

total number of students surveyed = $\frac{144(100)}{24}$ = 600

(g) given, total number of students who have selected their favourite food as pizza or noodles = 156

% of students who have selected their favourite food as pizza or noodles = 15+24 =39%

total number of students surveyed = $\frac{156(100)}{39}$ = 400

% of students whose favourite food is ice cream = 20

hence, number of students whose favourite food is ice cream = $\frac{20(400)}{100}$

= 80

(h) given,  total number of students who have selected their favourite food as pasta or chocolates = 123

%  of students who have selected their favourite food as pasta or chocolates  = 18+23 = 41

total number of students surveyed = $\frac{123(100)}{41}$ = 300

% of students whose favourite food is noodles = 24

hence, number  of students whose favourite food is noodles = $\frac{24(300)}{100}$

= 72
