Time taken by Lipika to read a book =134 hours
She reads the entire book in 6 days.
Now, total number of hours she took to read the entire book
=134×6=74×6=212=1012 hours
Now if she reads for 12 hours daily, time required by her to complete the book
=1012÷ 12=212÷12=21
Hence, if she reads for half an hour daily she will finish reading the book in 21 days.
