I don't see how you can approach this question without knowing what are concentrations of both - or at least what is their ratio. What they say is - assume concentration ratio 1:1.

If you don't see how it works, try to solve the problem without knowing anything about C_acid and C_base. You won't move far.

I solved it
I am just intrigued as to why they said "same concentration"

I still fail to see what you are asking.

If they would say "different concentrations" there would be no solution.
