<gadget id="calculator">10 / 100</gadget>
<output>1/10 = around 0.1</output>

<gadget id="calculator">69 * (1/10)</gadget>
<output>69/10 = around 6.9</output>

<gadget id="calculator">69 - (69/10)</gadget>
<output>621/10 = around 62.1</output>

<gadget id="calculator">(621/10) - 56.16</gadget>
<output>5.94</output>

<gadget id="calculator">5.94 / (621/10)</gadget>
<output>0.095652</output>

<gadget id="calculator">0.095652 * 100</gadget>
<output>9.5652</output>

<result>D</result>
the list price of an article is rs. 69. a customer pays rs. 56.16 for it. he was given two successive discounts, one of them being 10 %. the other discount is?
multiply(divide(subtract(subtract(69, multiply(69, divide(10, const_100))), 56.16), subtract(69, multiply(69, divide(10, const_100)))), const_100)
"69 * ( 90 / 100 ) * ( ( 100 - x ) / 100 ) = 56.16 x = 9.56 % answer : d"
