Hi all! Here is another logic Q for students to try. Same as the previous time, dont spoil the chance for others to try. Just comment Got it if student has gotten the answer. Only this time, record the time the student took to get the ans! Ding Dong and Dong Ding went to a bookstore, and found a limited edition comic book. The following shows their conversation: Ding Dong: Dong Ding, lets get this book! But I am short of money... Dong Ding: Oh no! I want to buy the book too! Since I am also short of money, lets buy just 1 book with our money together! Ding Dong: Sure! I am only $9.90 short. Dong Ding: Well... I am only $0.10 short. Ding Dong: Gosh... Seems like we cant even buy 1 book together... Q: How much does the comic book cost? (Assume all prices in the bookstore are in units of $0.10)
