Lipika reads a book for (1)3/4 hours everyday. She reads the entire book in 6 days. How many hours in all were required by her to read the book?

Time taken by Lipika to read a book = (1)3/4 hours.
She reads entire book in 6 days.
Now, total hours taken by her to read the entire book = (1)3/4×6
= 7/4×6=21/2=10(1/2) hours
Thus, 10 hours were required by her to read the book.
