By weight, liquid X makes up 0.8 percent of solution A and 1.8 percent of solution B. If 300 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:
A) 1.5% B) 1.9% 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 1.5% + 1.8% of Weight of B   When 300gms of 1.5% and 700gms of B is mixed :   Weight of Liquid X = (0.8 * 300)/100 + (1.8* 700)/100=

<output>15</output>
15gms   % of Liquid X in resultant mixture= (15/1000) *100=

<output>3/2 = around 1.5</output>
