Let the consumption of sugar originally be 1 unit and let its cost be ₹ 100.

New cost of 1 unit = ₹ (100 + 20) = ₹ 120

Now, ₹ 120 yeild 1 unit of sugar

•°• ₹ 100 will yeild (1/120 × 100) unit = 5/6 unit of sugar

Reduction in consumption

$\bf{ = 1 - \frac{5}{6}} \\ \\ \bf{= \frac{6 - 5}{6}} \\ \\ \bf{= \frac{1}{6} \: \: unit}$

•°• Reduction % in consumption

$\bf{ = ( \frac{1}{6} \times \frac{1}{1} \times 100)\%} \\ \\ \bf{= \frac{50}{3} \%} \\ \\ \bf{= 16 \frac{2}{3} \%}$
