No, the answer must be A3B2C11.
Indian_Dragon,it seems for B atoms you have considered only "opposite edge centeres" and not "diagonally opposite edge centres".

EVEN I REALLY DID NOT GET WHAT DIAGONALLY OPPOSITE MEANS AND I THINK EVERY ONE IS DOING A MISTAKE
WHEN YOU GET A AS 6x1/8 I DO NOT THINK THAT YOU CAN SIMPLIFY AND WRITE IT AS 3/4 AS WE ARE TRYING TO FIND MOLECULAR FORMULA AND NOT EMPERICAL FORMULA AND HENCE IF THE ANS DOES COME TO eg. A8B16C4 THAT WILL BE THE ANS AND NOT A2B4C
PLEASE CORRECT ME IF I AM WRONG
