Amount of soda in 250 litres mixture = $$frac{7}{(7+18)} imes250=70$$ litres => Amount of water = $$250-70=180$$ litres Let $$x$$ litres of soda is added. => $$frac{70+x}{180}=frac{2}{3}$$ => $$210+3x=360$$ => $$3x=360-210=150$$ => $$x=frac{150}{3}=50$$ $$ herefore$$ 50 litres of soda should be added. => Ans - (D)
