Dear Sir,
Now as the teachers are evaluating business studies paper 2015, the answer key provided by the board is faulty in case of All India sets. The solution to Q no 13, Business studies, All india Set no 1 (2015) is Personal Barrier. Where as in the answer key provided by board its Organisational Barrier. The same question is also asked in other two sets of All India. Please check the answer key again.
Regards
Mona Batra
