is the solutions fully dissociating as in strong acid or is it a weak acid?
If strong acid then Philips anser is correct.

Not at all possible.. More data is missing then
It can never be basic.

see strong acids and weak acids were based on pH values na.
in the first soln we have [H+]=10-2 per lit
in the second soln we have [H+]=10-5 per lit
finally we have [H+]=1/2(1.001 x 10^-2)
so pH≈2.3
