(d) None

Let x litres of the 37.85% alcoholic solution and (35 – x) litres of 92% alcoholic solution be required to get 35 L of 89% solution. Then, 37.85% of x + 92% of (35 – x) = 89% of 35

\(\Rightarrow\) \(\frac{37.85X}{100}\)\(\frac{92\times35}{100}\) - \(\frac{92\times X}{100}\) = \(\frac{89}{100}\) x 35

\(\Rightarrow\) 54.15x = 105  \(\Rightarrow\) x = \(\frac{105}{54.15}\) = 1.94 L (approx.)
