Correct answer: B

Step-by-Step Solution

To calculate the total money saved, we must find the total discount amount applied to the initial bill.

  1. Calculate Initial Bill:

    • Dilshan bought books worth 520, 450, and 250.

    • Initial Bill = 520 + 450 + 250 = 1220.

  2. Calculate First Discount (10% on all books):

    • First Discount = 10% of 1220 = 0.10 * 1220 = 122.

    • Remaining Bill after first discount = 1220 - 122 = 1098.

  3. Calculate Second Discount (5% on initial bill condition):

    • The problem states an additional 5% on the initial bill if it is greater than or equal to 1000. Since 1220 >= 1000, the condition applies.

    • Note on interpretation: Based on the options and the solution, the second discount is calculated on the remaining bill amount after the first discount.

    • Second Discount = 5% of 1098 = 0.05 * 1098 = 54.9.

  4. Calculate Total Savings:

    • Total Savings = First Discount + Second Discount

    • Total Savings = 122 + 54.9 = 176.9.
