<gadget id="calculator">32 * 20</gadget>
<output>640</output>
640   Now increase in avg= 4 runs. So, new avg = 32+8= 
<gadget id="calculator">32+8</gadget>
<output>40</output>
40 runs   Total runs= new avg x new no. of innings = 40 * 21= 
<gadget id="calculator">40 * 21</gadget>
<output>840</output>
840   Runs made in the 11th inning= 840-640= 
<gadget id="calculator">840-640</gadget>
<output>200</output>
