Answer:
$1,000 gain
Step-by-step explanation:
The cost basis for the vehicles was $6,000 and the carrying cost was $4,000 = $2,000 depreciation
If they sold the vehicles for $5,000, then they had a $1,000 gain (= $5,000 - $4,000). The journal entries should be as following:
Dr Cash account 5,000
Dr Accumulated Depreciation account 2,000
Cr Motor Vehicles account 6,000
Cr Gain on Motor Vehicles 1,000
