Answer: (1) 8.5 %

Explanation:-
List price pf a book = Rs. 100
Therefore, the list price 3 books = 3 x 100
= Rs. 300

The selling price of 3 books = Rs. 274.5
Discount = 300 – 274.5 = Rs. 25.5
Then, the percentage of discount = 25.5 x 100/300
= 8.5%

Then, the rate of discount is 8.5%.

Hence, the answer is (1) 8.5%
