A) 200
B) 160
C) 100
D) 65
E) 50
<gadget id="calculator">75 / 100</gadget>
<output>3/4 = around 0.75</output>

<gadget id="calculator">45 / 100</gadget>
<output>9/20 = around 0.45</output>

<gadget id="calculator">60 / 100</gadget>
<output>3/5 = around 0.6</output>

<gadget id="calculator">(9/20) / (3/5)</gadget>
<output>3/4 = around 0.75</output>

<gadget id="calculator">(3/4) / (3/4)</gadget>
<output>1</output>

<output>100</output>

<result>C</result>
if 45 % of z is 60 % of y and y is 75 % of x, what percent of x is z?
multiply(divide(divide(75, const_100), divide(divide(45, const_100), divide(60, const_100))), const_100)
"( 45 / 100 ) z = ( 60 / 100 ) y and y = ( 75 / 100 ) x i . e . y = ( 3 / 4 ) x i . e . ( 45 / 100 ) z = ( 60 / 100 ) * ( 3 / 4 ) x i . e . z = ( 60 * 3 ) x / ( 45 * 4 ) i . e . z = ( 1 ) x = ( 100 / 100 ) x i . e . z is 100 % of x answer : option c"
