Answer 1

Question 1

9 students chose accountancy

33.33% chose business studies

question 2

9 books

Explanation:

Question 1

we interpret the question as it is.

Business student = 1/3 X 24

= 8 students

Media = 1/6 x 24

= 4 students

Retail= 1/8 X 24

= 3 students

to get the students who chosen accountancy we need to add those that chosen other disciplines and subtract from the total number of students

24 - (8+4+3)

= 9 students chose accountancy

percentage for business studies = 8/24 X 100%

= 33.33%

Question 2

Blue = 1/5 X 40

= 8 books

Green = 30/100 X 40

= 12 books

Red = 20/100 X 40

= 8 books

books of other colours = 40 - (8+12+8+3)

= 9 books
