Solution ''X'' contains `Na_(2)CO_(3)` and `NaHCO_(3),  20 ml` of X when titrated using methyl organge indicator consumed 60 ml of 0.1M HCI solution. In another experiment, 20 ml of X solution when titrated using phenolphthalein consumed 20 ml of `0.1 M HCl` solution. The concentraions `("in mol lit"^(-1))` of `Na_(2)CO_(3) and NaHCO_(3)` in X are respectively)
