<gadget id="calculator">32 * 20</gadget>
<output>640</output>
640   Now increase in avg= 4 runs. So, new avg = 32+6= 
<gadget id="calculator">32+6</gadget>
<output>38</output>
38 runs   Total runs= new avg x new no. of innings = 38 * 21= 
<gadget id="calculator">38 * 21</gadget>
<output>798</output>
798   Runs made in the 11th inning= 798-640= 
<gadget id="calculator">798-640</gadget>
<output>158</output>
