The value of the supply made by the principal shall be four thousand five hundred and fifty rupees per quintal or where he exercises the option, the value shall be 90 per cent. of five thousand rupees i.e., four thousand five hundred rupees per quintal.
- where the value of a supply is not determinable under clause (a), the same shall be determined by the application of rule 30 or rule 31 in that order.
