the price of an item is discounted 10 percent on day 1 of a sale. on day 2, the item is discounted another 20 percent, and on day 3, it is discounted an additional 40 percent. the price of the item on day 3 is what percentage of the sale price on day 1?  Choose the correct option:
A) 28 %	B) 48 %	C) 64.8 %	D) 70 %	E) 72 %
<gadget id="calculator">40 / 100</gadget>
<output>2/5 = around 0.4</output>

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

<gadget id="calculator">1 - (1/10)</gadget>
<output>9/10 = around 0.9</output>

<gadget id="calculator">(2/5) / (9/10)</gadget>
<output>4/9 = around 0.444444</output>

<gadget id="calculator">(4/9) * 100</gadget>
<output>400/9 = around 44.444444</output>

<gadget id="calculator">(400/9) + 2</gadget>
<output>418/9 = around 46.444444</output>

<result>B</result>
the price of an item is discounted 10 percent on day 1 of a sale. on day 2, the item is discounted another 20 percent, and on day 3, it is discounted an additional 40 percent. the price of the item on day 3 is what percentage of the sale price on day 1?
add(multiply(divide(divide(40, const_100), subtract(1, divide(1, 10))), const_100), 2)
let initial price be 1000 price in day 1 after 10 % discount = 900 price in day 2 after 20 % discount = 720 price in day 3 after 40 % discount = 432 so , price in day 3 as percentage of the sale price on day 1 will be = 432 / 900 * 100 = > 48 % answer will definitely be ( b )
