Given,

2016 is the base year

The price of the basket of goods in 2016 = Quantity of Chocolates in 2016 x Price of chocolates in 2016 + Quantity of Cheese in 2016 x Price of Cheese in 2016 = 150 x €10.50 + 45 x €15.00 = €1575 + €675 = €2250

As 2016 is the base year, the CPI in the base year = 100 = CPI in 2016

The price of the basket of goods in 2017 = Quantity of Chocolates in 2016 x Price of chocolates in 2017 + Quantity of Cheese in 2016 x Price of Cheese in 2017 = 150 x €13.00 + 45 x €17.00 = €1950 + €765 = €2715

CPI in 2017 = Price of the basket of goods in 2017/Price of the basket of goods in the base year(2016) x 100 = €2715/2250 x 100 = 120.67

Inflation rate in 2017 = (CPI in 2017 - CPI in 2016)/CPI in 2016 x 100 = (120.67-100)/100 x 100 = 20.67% = 20.7% (rounded to the nearest one-tenth of one percent)
