The goods are not sold under a patent or trade name. When does section 16(1) of the Sale of Goods Act, 1930 imply a condition that they are reasonably fit for the buyer's particular purpose?

Section 16(1) of the Sale of Goods Act, 1930 implies a condition of reasonable fitness where the buyer makes the particular purpose known so as to show reliance on the seller's skill or judgment, and the goods are of a description the seller supplies in the course of business. Without reliance, or where the seller does not deal in such goods, the condition does not arise; examination by the buyer bears on merchantable quality under section 16(2).
