Yup I just solved it too using algebra but I was using the ratio of 5/3 instead, but same same. Any way to solve this without algebra? I can’t seem to find a way.

Understand if use 1 algebra, u is acceptable for P6. Unless using 2 algebra x and y in secondary school.

I see. The answer key somehow figured out this by doing:
45/5=9
9*19=171

Any idea how to get 19 units?
