Calculating the Second Discount Rate:

Given Information:
- Printed price of the calculator: 225
- Retailer's cost price after the first discount: 148.5
- First discount rate: 20%

Calculating the First Discount:
- Price after 20% discount = 225 - (20/100 * 225) = 225 - 45 = 180

Calculating the Second Discount Rate:
Let the second discount rate be x%.
- Price after the second discount = 148.5
- Price after both discounts = 180 * (1 - x/100) = 148.5
- Solving for x, we get: x = 17.5%
Therefore, the second discount rate is 17.5%.
This calculation is derived from the fact that the retailer pays 148.5 for the calculator after both discounts, which can be represented by the equation 180 * (1 - x/100) = 148.5. By solving for x, we find that the second discount rate is 17.5%.
