Answer:
$40,000 gain
Explanation:
For computing the gain or loss on disposal, first we have to calculate the depreciation expense which is shown below:
= (Original cost - residual value) ÷ (useful life)
= ($600,000 - $100,000) ÷ (5 years)
= ($500,000) ÷ (5 years)
= $100,000
For 6 months it would be $50,000
Now the gain or loss would be
= Sale value of machinery - (original cost - accumulated depreciation balance - depreciation expense)
= $240,000 - ($600,000 - $350,000 - $50,000)
= $240,000 - $200,000
= $40,000 gain
