if non current is sold & there is any profit again , does it affect asset and equity but not liability ? . if current asset is sold it affect all asset, liability and equity ?
Selling any type of asset does not affect liabilities. Selling a current asset does not affect equity unless it is sold at a profit which is only going to happen if it is inventory.
