Answer:
$2,200,000 gain
Step-by-step explanation:
When the amount received from the disposal of an asset is lower than the carrying or net book value (NBV) of the asset, the company makes a loss on disposal otherwise, the company makes a gain on disposal.
The carrying amount of the asset is the difference between the asset's cost and accumulated depreciation as at the date of disposal.
Asset NBV = $2,000,000 - $1,200,000
= $800,000
Gain/(loss) on disposal = $3,000,000 - $800,000
= $2,200,000
