A dishonest dealer claims to sell a product at its cost price. He uses a counterfeit weight which is 20% less than the real weight. Further greed overtook him and he added 20% impurities to the product. Find the net profit percentage of the dealer?
Can someone please tell me how to arrive at the answer? I'm repeatedly getting 56.25.
My approach, Say the CP is C For 1kg. Now if he is using a tainted weight then the SP would be C for 0.8 kg. He again adds 20% impurities. So 20% if 0.8 = 0.16 kg. (0.8 - 0.16) = 0.64 kg which he sells for C. From this we can say the SP of 1kg as 100C/64 (SP-CP/CP) *100 we get 56.25 %
Would be great if you could tell me what is wrong with my method and solve it on similar terms.

I feel the OA is incorrect I was getting 56.25% as both the profits should be successive (that's what I feel 25% profit by each cheating)

The dealer uses weight which is 20% less than the real weight. or (1- 1/5) or 4/5 of real weight. It means that he is selling $4 worth of product for $5.
The dealer then further added 20% impurities to the product. It means that he is selling $5 worth of product for $6.
So his profit is $6-$4 = $2 and his profit percent is (2/4)*100 = 50%
Answer:- C
