When the price of petrol increases by 10% and then by another 10%, you can calculate the total percentage increase as follows:
1. First, you increase the price by 10%: 100% (original price) + 10% = 110%.
2. Then, you increase the result by another 10%: 110% + 10% = 121%.
So, the total percentage increase in the price of petrol is 121%.
