Answer:
a. Gain on Sale of Land 20,000
Land 20,000
Step-by-step explanation:
The Gain on Sale of land account should be debited by the gain received to remove the effects from the statements as the account had been credited.
The Land account should likewise be credited as the gain had been debited to it. Crediting it would therefore remove the effects of the sale of the land.
Difference = 70,000 - 50,000
= $20,000
