(a) Cost price = Rs \(250\)
Selling price = Rs \(325\)
Profit = \(325 - 250\) = Rs \(75\)
\(\text{Profit\%}=\frac{\text{Profit}}{\text{CP}}\times100\)
= \(\frac{75}{250}\times100\)
= \(30\%\)
(b) Cost price = Rs \(12000\)
Selling price = Rs 13,500
Profit = \(13500-12000= \)RS \(1500\)
\(\text{Profit\%}=\frac{\text{Profit}}{\text{CP}}\times100\)
Profit % = \(\frac{1500}{12000}\times100=12.5\%\)
(c) Cost price = Rs \(2500\)
Selling price = Rs \(3000\)
Profit = \(3000 - 2500\) = Rs \(500\)
\(\text{Profit\%}=\frac{\text{Profit}}{\text{CP}}\times100\)
Profit % = \(\frac{500}{2500}\times100=20\%\)
(d) Cost price = Rs \(250\)
Selling price = Rs \(150\)
Loss = \(250 - 150\) = Rs \(100\)
\(\text{Loss\%}=\frac{\text{Loss}}{\text{CP}}\times100\)
Loss % = \(\frac{100}{250}\times 100=40\%\)
