Electives

28 students choose elective B.

24 students went to elective A.

An intermediate school has ten classes with 24 students in each.

Instead of regular classes, it is offering 6 ‘electives’ for a week when 20% of the students will be away for an inter-school sports exchange.

0.125 of the students who will remain at school, have chosen to take elective A.

One sixth of the students chose elective B.

The rest of the students all chose the four electives, C, D, E and F in an exactly even split.

How many students can the teachers taking C expect in their elective?

48 students aren’t at school for inter-school sports.

35 students are in C.

35 students are in E.

35 students are in D.

35 students are in F.

20% of 240 = 48

240 - 48 = 192

192 - 24 = 168

⅙ of 168 = 28

140 left

140 ÷ 4 = 35.

Today I was finding out the answer to the problem above and I had worked with my friend Alex he helped me work out the things that you see above.
