define the small business as per oldnew classification
The term "old new" as used in the question is not clear. Please recheck your question. However, the definition used by the Government of India to define a small industry/business is as follows.
Industries where the amount invested in the fixed assets (particularly plant and machinery) is less than Rs. 1 crore are regarded as small-scale industries. However, export-oriented units that use modern production techniques are considered as small-scale industries if their investment does not exceed Rs. 5 crore.
