<gadget id="calculator">48 / 16</gadget>
<output>3</output>
3 units / day   Capacity of P= 48 / 24= 
<gadget id="calculator">48 / 24</gadget>
<output>2</output>
2 units / day   Capacity of J, P, H= 48 / 8= 
<gadget id="calculator">48 / 8</gadget>
<output>6</output>
6 units / day   From the above capacity of H= 6 - 2 - 3= 
<gadget id="calculator">6 - 2 - 3</gadget>
<output>1</output>
1   So H takes   48 / 1= 
<gadget id="calculator">  48 / 1</gadget>
<output>48</output>
