Can someone help with this maths problem? P4 math problem. A total of 456 students and teachers visited the National Museum last weekend. There were 1/7 as many teachers as students and there were 5/7 more male teachers than female students. How many female students visited the National Museum last weekend?

Can be 7, 14, 21 or 28. There is no restricting condition on the female teachers and male students, hence no unique solution.

Hi Kevin, can you elaborate more about the various possible solutions?

Swee Chye Total of 456 teachers and students, 1/7 as many teachers as students: Total 456, Teachers 1 part -> 456 / 8 = 57 Students 7 part -> 7 x 57 = 399 "There were 5/7 more male teachers than female students" Means that: Male teachers 12 units Female teachers ? Total is 57 Female students 7 units Male students ???? Total 399 Since there is no restricting condition on female teachers and male students, The male teachers can be 12, 24, 36 or 48 when 1 unit = 1,2,3,4 respectively. Because of this relation, the female students can be 7, 14, 21 or 28 along with the corresponding u value.

The 12u cannot go beyond 60, else the solution will not exist.

Kevin Hzh Thanks for the breakdown and working. Can I check how do you get Male teachers 12 units (5/7 => 5+7=12?) and Female students 7 units (Students 7 part => Students 7 units?) Is that correct?

Yes. The key word lies with 5/7 more.

This is no longer in syllabus - Twice more or a fraction more. Anyway, it's a P6 concept - 1/7 as many teachers as students. FYI.
