A tradesman fixed his selling price of goods at 30% above the cost price. He sells half the stock at this price, one-quarter of his stock at a discount of 15% on the original selling price and rest at a discount of 30% on the original selling price. Find the gain percent altogether. Option 1) 15.675%Option 2) 15.40%Option 3) 15.575%Option 4) 16.375%Option 5) 14.875%

Revenue =   $\dpi{100} \left [ \left ( \frac{1}{2} \times 130\right )+\left ( \frac{1}{4} \times 130\times .85\right ) +\left ( \frac{1}{4}\times 130\times .7 \right )\right ]$
$\dpi{100} \Rightarrow 115.4$
