I really hope this solution helps you understand the concept of using similar ratios behind this question. If thw answer is by any chance incorrect I’d like to apologise and will relook at the question:)

I apologise, the answer is 25 as you need to add either Ben or Justina to the 24 we have found!

Hi, it's incorrect to say
Ben + 6 units=Just + 8 units
Becos 6 units cannot equal 8 units.
You'll have to change one of them to parts in order not to confuse the students.
