Molarity of H+ is 1 M in both
So molarity will remain same

whats wrong with following solution:

[(200*1)+(100*.5)]/300

after all molarity is moles per litre

why are we considering H+ and why not the compound as a whole?

as per defn.molarity=no of moles/vol of soln *1000...

here,acid strengh has not been asked for which we shall consider the H+ conc of the two solns....

The final molarity is 1.5M

@chill,molarity is defined for a particular sub(here for H⁺)
