Answer:
$500,000
Step-by-step explanation:
For Lindsey, the cost incurred in the acquisition of Donna's property via the exchange is
= $400,000 + $200,000
= $600,000
For Donna, the cost incurred in the acquisition of Lindsey's property via the exchange is
= $1,000,000 + $100,000
= $1,100,000
If no cash is exchanged, amount of gain recognized by Lindsey
= $1,100,000 - $600,000
= $500,000
