1. A collection of books went on sale and two-third 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?
- A. Tk 180
- B. Tk 180
- C. Tk 180
- D. Tk 180
Answer: Option D
Explanation:
Two y third were sold, so left = ( 1 - 2/3) = 1/3 of the book.
1/3 of total book = 36
total book = 36×3 = 108
Now, 2/3 of total book = 2/3×108 = 72
Total amount earned = 72×2.30 Tk. = 165.6 Tk
