Under the fixed capital method, the partners maintain two separate accounts: (1) Fixed Capital Account and (2) Current Account.
The Fixed Capital Account records only the permanent capital invested in the firm. This amount generally remains unchanged from year to year unless there is any additional capital introduced or any permanent withdrawal of capital. Therefore, Assertion (A) is correct because it rightly states that the fixed capital account stays the same (fixed) unless additional capital is introduced or withdrawn.
On the other hand, transactions like share of profit or loss, interest on capital, drawings, interest on drawings, salary or commission to partners, etc. are recorded in the partners’ current accounts under the fixed capital method. Hence, Reason (R) is incorrect as an explanation of Assertion (A). While Reason (R) is itself a true statement, it relates to the current account, not the fixed capital account.
Therefore, both Assertion (A) and Reason (R) are correct individually, but Reason (R) is not the correct explanation of Assertion (A). Hence, option (B) is correct.
