Acid Base Titration

10 ml of a mixture of Na2CO3 and NaHCO3 is titarted with 0.1 M H2SO4 solution. When phenolphthalein is used, it is observed that if 2.5 ml acid solution is added then the solution becomes colourless. After this when one drop of methyl orange is added, it is observed that if 2.5 ml more of 0.2 M H2SO4 is added then the solution becomes orange from yellow. In the mixed solution of Na2CO3 and NaHCO3, find out the strengths of Na2CO3 and NaHCO3 in Normality.
