A collection of books went on sale and 2/3 of them was sold for Tk 2.30 each. If none of the 36 remaining books were sold, what was the total amount received for the books that were sold?
Solution
Correct Answer: Option A
Remaining books = 1 - 2/3 = 1/3
1/3 of the books = 36 books
So, 2/3 of the books = 36×(2/3) / (1/3) = 72
∴ Total amount received for the sold books = 72 x 2.30 = 165.6 TK
