Hope this is correct and this helps :-)
This doesn't seem like a typical sec 4 qn, more of a JC2 P&C qn or sec sch SMO qn (most prob the former)

“Permutations and combinations” was a Sec 4 A Maths topic many many years ago in the 2000s; however, they excluded the cases for circular arrangements back then which was covered in JC H2 Maths.
As an added bonus, you may not know it, but set theory/notation and matrices were Sec 4 A Maths topics as well during that period of time (now Sec 4 E Maths topics); however, the Sec 4 A Maths syllabus had the solving of two simultaneous linear equations in two unknowns by a matrix method which we do not see in Sec 4 E Maths matrices topic today.

Also, I’m not ruling out the possibility that Clara is taking the old A Maths syllabus code 4037 (ie Clara is an international student) or is practising questions from that syllabus (somehow).
The recent questions which Clara has posted seems to suggest this, because I have read the 4037 syllabus as recent as two years ago or last year in an online past year exams website for other countries’ O Levels (before they changed the link and no longer allowed access to the general public last year).
In fact, the syllabus in the 2000s was called 4037. As comparison, the current syllabus is 4049 and the previous one was 4047.
