Chemical Equilibrium

Observe the following equilibrium in a 1 L flask.
A(g)⇌B(g) At T(K), the equilibrium concentrations of A and B are 0.5 M and 0.375 M respectively. 0.1 moles of A is added into the flask and heated to T(K) to establish the equilibrium again. The new equilibrium concentrations (in M ) of A and B are respectively
