<gadget id="calculator">134/100*100</gadget>
<output>134</output>
134   10% discount   Then price= 134 * 90/100= 
<gadget id="calculator">134 * 90/100</gadget>
<output>603/5 = around 120.6</output>
120.6   15 % discount   Then price= 120.6 * 85/100= 
<gadget id="calculator">120.6 * 85/100</gadget>
<output>102.51</output>
102.51   So Gain= 102.51 - 100= 
<gadget id="calculator">102.51 - 100</gadget>
<output>2.51</output>
2.51   Gain %= Gain * 100 /CP   ==&gt; 2.51 * 100 /100= 
<gadget id="calculator">2.51 * 100 /100</gadget>
<output>2.51</output>
