Choose the correct choice from the following choices

Purchase cost = 600/1500= 
<gadget id="calculator">600/1500</gadget>
<output>2/5 = around 0.4</output>
$ 0.4   25% above the cost per head= (125/100)*0.4= 
<gadget id="calculator">(125/100)*0.4</gadget>
<output>0.5</output>
$ 0.5   2/3 of the heads were sold means 2/3*1500= 
<gadget id="calculator">2/3*1500</gadget>
<output>1_000</output>
1000 ,Selling amount for 1000 cabbage= 1000 * 0.5= 
<gadget id="calculator">1000 * 0.5</gadget>
<output>500</output>
$ 500   Remaining were sold at a price equal to 40% less than the price each head sold for on the day before i.e , (60/100)*0.5= $ 0.3   Hence selling cost for the remaining cabbage = 500 * 0.3= 
<gadget id="calculator">500 * 0.3</gadget>
<output>150</output>
$ 150   Total selling cost= 500 + 150= 
<gadget id="calculator">500 + 150</gadget>
<output>650</output>
$ 650   Gross profit= $ 650 - $ 600 = $ 50   Hence Answer is d $50.
