X is demand curve
Y is supply curve
Z is supply curve

The supply curve shift from Y to Z

Before the introduction of subsidy
$15×20 = $300

After the introduction of subsidy
$10×40 = $400

Percentage increase = $400-$300 = $100
100/300 × 100/1 = 33.3%

% change in quantity demanded/ % change in price = 100/33.3 = 3.0

% change in quantity demanded= change/old × 100/1
= 20/20 × 100/1
= 100%

% change in price = change/old × 100/1
= 5/15 × 100/1 = 33.3%
