850 plus 1,759 = 2,609
Expressed as a percentage, 150/850 x 100 = 17.6470588235294117 recurring (that is, 17.64705882352941176470588235294117...) percent.
850!!
36880 + 850 = 37730
850+1766 = 2616
571+d = 850 d = 850 -571 d = 279

(p+150) + q = 1000 p+q= 1000-150 =850 Value of q is 425 and value of p 425 plus 150 ie. 575
600 + 250 = 850
Concentration is 150 gm solute per 850 mL solvent: 150 g solute per (150g + 850g =) 1000 g solution = 15% (m/m) CaCO3, since 850 mL is equal to (rounded) 850 grams.However calcium carbonate is rather INsoluble (smaller than 0.15 g/100 mL, about 0.15%) so this answer is physically impossible to achieve.If the question was mistyped and could have been 150 mg(= milligram, not gm = gram) per 850 mL, THEN the answer would have been 0.15 g per (850g + 0.15g =) 850 g solution which is (100%*0.15/850=) 0.018% CaCO3
