Question

A person sells two fans for Rs. 6800. The cost price of the first fan is equal to the selling price of the second fan. If the first is sold at 30% loss and the second at 100% gain, what is total profit or loss (in rupees)?

Answer 1

Let the cost price of First fan be $C1$ and cost prive of second fan be $C2$

Accotding to question $C1$ $=$ $\frac{2}{1}C2$

Also $C1+C2=6800$

So we have $C2=\frac{6800}{3}$ and $C1=\frac{13600}{3}$

Loss on first fan $=\frac{3}{10}\times \frac{13600}{3}=1360$

Gain on Second fan $=\frac{6800}{3}$

So Net Profit $=\frac{4720}{3}$ Rs
