A 100 ml mixture of `Na_(2)CO_(3)` and `NaHCO_(3)` is tittrated against 1 M HCl. If `v_(1)L` and `v_(2)L` are consumed when phenolphthalein and methyl orange are used as indicators respectively in two separate titrations, which of the following is true form molarities in the original solution.

A

molarity of `Na_(2)CO_(3)=20v_(1)`

B

molarity of `NaHCO_(3)=10(v_(2)-2v_(1))`

C

molarity of `Na_(2)CO_(3)=10(v_(2)+v_(1))`

D

molarity of `NaHCO_(3)=10(v_(2)-v_(1))`
