Practicing Success
If the tax on a commodity is diminished by 20% and its consumption increased by 15%, the revenue decreases by: |
8% 12% 10% 6% |
8% |
Let initial price = 100x Final price = 100x × \(\frac{80}{100}\) × \(\frac{115}{100}\) = 100x × \(\frac{4}{5}\) × \(\frac{23}{20}\) = 92x Required percentage = \(\frac{100-92}{100}\) × 100 = 8% |
