Marked price of a radio = Rs.480
Therefore, SP of a radio = \( \Large 480 \times \left(\frac{100-10}{100}\right) \)
= \( \Large \frac{480 \times 90}{100} \) = Rs.432
= CP of a radio = \( \Large \frac{432 \times 100}{100+8} \)
= \( \Large \frac{432 \times 100}{108} \) = Rs.400
Profit when article is sold at MP
= 480 - 400 = Rs.80
Hence, profit per cent
= \( \Large \frac{80}{400} \times 100\% \) = 20%
