The answer is 16 2/3.

Here's the step-by-step solution:

1. Let's assume the original price of petrol is $1 per litre. So, for $100, a person could buy 100 litres of petrol.

2. After a 20% increase, the new price of petrol is $1.20 per litre. So, for $100, a person can now buy approximately 83.33 litres of petrol.

3. To find out how much the person needs to reduce his consumption, we calculate the difference between the original quantity (100 litres) and the new quantity (83.33 litres), which is 16.67 litres.

4. To express this as a percentage, we divide 16.67 by the original quantity (100 litres) and multiply by 100, which gives us approximately 16.67%, or 16 2/3% when expressed as a mixed number.

So, a person must reduce his consumption by approximately 16 2/3% to keep his expenditure on petrol the same after a 20% price increase.
