Answer:
Consider the following calculations
Step-by-step explanation:
Step 1. Given information. 
Asset Cost Adjusted Basis
--------------------------------------------------
Skidder 230,000 40,000 
Driller 120,000 60,000 
Platform 620,000 0
-------------------------------------------------
Total 970,000 100,000 
Step 2. Formulas needed to solve the exercise. 
Allocation for each asset = value sold * (adjusted basis / total) 
Gain on sale = Sales price - Adjusted basis amount 
Step 3. Calculation and Step 4. Solution. 
Sales price is allocated on the basis of adjusted value. 
 
- Skidder = 300.000 * 40.000/100.000 = 120.000 
 
 
- Driller = 300.000*60.000/100.000 = 180.000 
 
 
- Platform = 300.000*0/100.000 = 0 
 
 
Gain on sale = Sales price - Adjusted basis amount 
 
 = 300.000 - (40.000 + 60.000 + 0) 
 
 = 200.000
