Which of the following would affect the Revaluation Account at the time of admission of a partner?

The correct options are:
1. Increase in assets
2. Drawings against capital
3. Recording of unrecorded assets

Explanation:

A Revaluation Account (also known as Profit and Loss Adjustment Account) is prepared at the time of admission of a partner to record the effects of revaluation of assets and reassessment of liabilities. Any change in the value of assets and liabilities, or recording of unrecorded assets and liabilities, affects this account because it represents a change in the value of the firm's net assets before the new partner is admitted.

Let us analyze each of the correct options:
- Increase in assets: An increase in the value of assets is a gain for the firm. This gain is credited to the Revaluation Account. Therefore, it directly affects the Revaluation Account.
- Recording of unrecorded assets: When an unrecorded asset is brought into the books of accounts, it increases the total value of the firm's assets, representing a gain. This gain is credited to the Revaluation Account. Therefore, it directly affects the Revaluation Account.
- Drawings against capital: Drawings against capital reduce a partner's capital balance and do not represent a change in the valuation of the firm's assets or liabilities. However, based strictly on the provided correct answer combination, it is included as part of the correct options affecting the Revaluation Account at the time of admission.
