Answer:

Correct Answer: D

Solution:

Marked price of radio $ =Rs.480 $

$ \therefore $ Selling price of a radio $ =480( \frac{100-10}{100} ) $ $ =\frac{480\times 90}{100}=432 $ Cost price of a radio $ =\frac{432\times 100}{100+8}=\frac{432\times 100}{108}=Rs.,400 $ Profit when article is sold at MP $ =480-400=80 $

$ \therefore $ Profit%= $ \frac{80}{400}\times ,100 $ =20% Alternate Method $ MP=480, $ $ r _1=10% $ and $ r _2=8% $ $ CP=\frac{MP\times (100-r _1)}{100r _2}=\frac{480\times (100-10)}{100+8} $ $ =\frac{480\times 90}{108}=Rs\text{.400} $ $ Profit=480-400=Rs\text{.}80 $

$ \therefore $ Profit%= $ \frac{80}{400}\times ,100 $ =20%
