Final answer:
Ramona's tax basis in the stock received in return for the contribution of property to the corporation is $362,500.
Step-by-step explanation:
Ramona's tax basis in the stock received in return for the contribution of property to the corporation is $362,500. The tax basis for each asset contributed to the corporation is determined based on the fair market value (FMV) at the time of contribution. Since Ramona contributed cash of $290,000 and Hermione contributed a building and land with a total FMV of $362,500, the tax basis for Ramona's stock is equal to the total FMV of the contributed assets.
