By weight, liquid X makes up 0.8 percent of solution A and 1.8 percent of solution B. If 500 grams of solution A are mixed with 700 grams of solution B, then liquid X accounts for what percent of the weight of the resulting solution?
Choose the correct choice from the following choices.
A) 1.66%
B) 1.96%
C) 10%
D) 15%
E) 19%
I think there is a typo in question.   It should have been "By weight Liquid 'X ' makes up..... "   Weight of Liquid X = 0.8 % of Weight of 1.66% + 1.8% of Weight of B   When 500gms of 1.66% and 700gms of B is mixed :   Weight of Liquid X = (0.8 * 500)/100 + (1.8* 700)/100=

<output>16.6</output>
16.6gms   % of Liquid X in resultant mixture= (16.6/1000) *100= 
<gadget id="calculator">(16.6/1000) *100</gadget>
<output>1.66</output>
1.66%   1.66%
<result>A</result>
