Wholesaler estimates its only 4 % apples supplied by him are defected so prior to the random sample of 600 apples he is stating that 4 apples per hundred are defective
(Therefore the supplier stated that out of 600 apples = 24 apples will be found defective prior to test.)
When a random inspection of 600 apples is completed is is found that 36 apples are found to defective and not 24.
This error when calculated was found to be 6% defective instead of the suppliers 4%. This is a effor of 50% increase of the suppliers figures.
From the expected 24 apples or 4% (the supplier estimate was incorrect and had increased by 50 %) to 36 apples or 6% found in the random test of 600 apples.

Answer:
The claim of the wholesaler is wrong. 6% of apples were found defective.
Explanation:
Given
Wholesaler claims it only 4 % of apples have defects.
It means 4 apples per hundred are defective
Step 1
Out of 600 apples = 24 apples will be found defective.
When a random inspection of 600 apples is completed is found that 36 apples are found to be defective and not 24.
This error when calculated was found to be 6% defective instead of the supplier's 4%. This is an effort of 50% increase of the supplier's figures.
Step 2
From the expected 24 apples or 4% (the supplier estimate was incorrect and had increased by 50 %) to 36 apples or 6% found in the random test of 600 apples.
Hence, the claim of the wholesaler is wrong. 6% of apples were found defective.
