# A merchant bought two transistors, which together cost him Rs. 480. He sold one of them at a loss of 15% and other at a gain of 19%. If the selling price of both the transistors are equal, find the cost of the lower priced transistor. Option 1) Rs. 300Option 2) Rs. 180Option 3) Rs. 200Option 4) Rs. 250Option 5) Rs. 280

Let CP of one Transistor = $x$
Another transistor = $\dpi{100} 480-x$
Now   $\dpi{100} x\times \frac{85}{100}=(480-x)\times \frac{119}{100}$
$\dpi{100} x=280\; \; another=200$
