Choose the correct option
A) 35.5% B) 40.0% C) 46.0% D) 49.5% E) 51.0%
Facebook : 50% of 300 friends liked my post, hence  0.50*300= 
<gadget id="calculator"> 0.50*300</gadget>
<output>150</output>
150 friends liked.   Twitter : 42% of 300 friends liked my post, hence  0.42*300= 
<gadget id="calculator"> 0.42*300</gadget>
<output>126</output>
126 seeds germinated.   Thus (friends who liked my post) /(total)= (150 + 126)/(400 + 300) = 276/600 = 46% seeds germinated.   Answer: 46.0%.
