Choose the correct choice from the following:
A) 45.5%  B) 46.5%  C) 48.0%  D) 49.5%  E) 51.0%

<gadget id="calculator"> 0.57*200</gadget>
<output>114</output>
114 pages read.   42% of 300 pages in science book, hence  0.42*300= 
<gadget id="calculator"> 0.42*300</gadget>
<output>126</output>
126 pages read   Thus (total read)/(total)= (114 + 126)/(200 + 300) = 240/500 =   48% pages read   Answer: 48.0%.
