A dealer offers a cash discount of \(20\) % and still makes a profit of \(20\) %, when he further allows \(16 \) articles to a dozen to a particularly sticky bargainer. How much per cent above the cost price were his wares listed ?
Answer: A
MP \(= \frac{120}{(\frac{80}{100})} = 150\)
Now he is selling 16 goods to a dozen(ie 12),
so his loss \(= {\frac{(16-12)}{16}} \times 100 = 25\) %.
Then the actual MP \(\frac{150}{(\frac{75}{100})} = 200\)
Hence, he has marked the MP \(100\) ?ove the CP.
