The total salary pool allocated to employees after headcount reduction is what percent of that before the headcount reduction?	Select.
A) 98.5%  B) 100.1%  C) 102.8%  D) 104.5%  E) 105.0%
100 employees getting 1000$ avg, so total salary for 100 ppl = 100000   9% reduction in employees lead to 91 employees and a salary increase of 10% of previous avg salary   Thus the new avg salary is = 10%(1000)+1000 = 1100   so total salary of 91 employees is   91*1100= 
<gadget id="calculator">  91*1100</gadget>
<output>100_100</output>
100100   Now the new salary is more than previous salary by x%. x= (100100/100000)*100= 
<gadget id="calculator">(100100/100000)*100</gadget>
<output>1_001/10 = around 100.1</output>
100.1%   So the Answer is 100.1%
<result>B</result>
