50ml of a solution containing 0.01mole each Na2CO3,NaHCO3 and NaOH was titrated with N-HCL.What will be reading if only Ph is used as indicator

first you need to do is 
equate the molarity or mole  equivalents of all the compounds present there,
Mequivalent of HCL =M equivalent of NaOH + M eqiuvalent of Na2CO3
                               =M equivalent of NaOH + M equivalent of NaHCO3
==> 1XV    = 1/40X 1000  + 1/106X 1000
                  =34ml
if you only phenophthalien indicator you will get the answer as 34ml
if you use methyl orange as an indicator you will get 55.77ml
