In case of admission of a partner, expenses on the revaluation account are paid by a partner named A of ₹3500, what will be the journal entry for this?

Revaluation A/c   Dr..    ₹3500
    To A's capital A/c                ₹3500
(Expenses of revaluation paid by partner)

The correct answer is option 3 i.e.
Revaluation A/c   Dr..    ₹3500
    To A's capital A/c                ₹3500
(Expenses of revaluation paid by partner)

Expenses are paid by partner; these are to be returned by the firm if it is mentioned in partnership deed. Expenses are losses for the firm that's why revaluation account is debited, and partners' capital A/c is credited.
