Answer:
Loss on disposal =$30,000
Explanation:
Present Value of the Note exchanged in Yr 3 = 0.75 x $600,000 =$450,000
Carrying Value of the Equipment sold = $480,000
Loss on disposal = $480,000- $450,000
= $30,000
Loss on disposal arises since the amount realized on the asset sold is less than it carrying value.
