$18\frac{1}{3}\%$ / $18\frac{1}{3}\%$
Correct Answer: $16\frac{2}{3}\%$ / $16\frac{2}{3}\%$
New consumption must be $\frac{1}{1.20} = \frac{5}{6}$ of the original, so the reduction $= 1 - \frac{5}{6} = \frac{1}{6} = 16\frac{2}{3}\%$. / नई खपत मूल की $\frac{1}{1.20} = \frac{5}{6}$ होनी चाहिए, अतः कमी $= 1 - \frac{5}{6} = \frac{1}{6} = 16\frac{2}{3}\%$।
