Answer:
Gopal reads for 13 / 4 hours per day. He is said to complete the book in 7 days. We are asked to find the number of days he has used to read the book.
This can be easily solved by Ratio and Proportion Method.
1 day = 13 / 4 hours :: 7 days = ? ( x )
Product of means = Product of extremes
=> 1 × x = 7 × 13 / 4
=> x = 7 × 13 / 4 hours
=> x = 91 / 4 hours
=> x = 22.75 hours ( or ) 22 ( 3 / 4 ) hours
So Gopal takes 22.75 hours to complete the book.
