A & B are partners sharing profits in the ratio of 1:2. C is admitted with a profit of 1/4 and take all share of B. If C's share for premium for goodwill is ₹25,000 and he does not bring this goodwill in cash, then what will be the journal entry?

C's Current A/c Dr.....    ₹25,000
    To B's Capital A/c                 ₹25,000
(Account of goodwill not brought in by new partner)

The correct answer is option 4-
C's Current A/c Dr.....    ₹25,000
    To B's Capital A/c                 ₹25,000
(Account of goodwill not brought in by new partner)

When goodwill does not exist in the books, sacrificing partners are credited with their share of goodwill and new partner is debited by the amount of goodwill not brought by him.
The journal entry in this case is :
Incoming (New) Partners Current A/c Dr.
   To Sacrificing Partners Capital A/c (individually)
(Account of goodwill not brought in by new partner)

So, In the above situation, C does not bring goodwill so his current account is debited with the amount of goodwill. Only partner B is sacrificing, so, only he will be compensated by new partner. 

The journal entry in this case will be-
C's Current A/c Dr.....    ₹25,000
    To B's Capital A/c                 ₹25,000
(Account of goodwill not brought in by new partner)
