Interest on capital has been credited @9% p.a. instead of 12 % p.a.
So, extra 3% will be credited which reduce profit of the firm to that extent.
That loss will be shared between partners in their profit-sharing ratio.
A will get credit of ₹3000 as interest on capital and debit of ₹3000 as share of loss,
B will get credit of ₹2400 as interest on capital and debit of ₹3000 as share of loss,
C will get credit of ₹2100 as interest on capital and debit of ₹1500 as share of loss,
So net effect is B will be debited with ₹600 and C will be credited with ₹600.
Adjustment entry will be passed in current account because their capitals are fixed.
