Question
Ravi has read 4/5 of a book while Saumya has read only
5/8 of the book she is reading. Both, however, have another 150 pages of their respective books remaining to be read. What fraction of the number of pages read by Ravi has been read by Saumya?Solution
Ravi has read 4/5 of a book. The remaining read of Ravi = (1-4/5) = 1/5 Saumya has read-only of the book The remaining read of Saumya = (1 - 5/8) = 3/8 Now, Total pages in Ravi's book 1/5 = 150 pages = 750 pages Total pages in Soumya's book  3/8 = 150 =400 pages Now, The fraction of the number of pages read by Ravi has been read by Saumya is. = (400 x 5/8)/ (750 × 4/5) = 250/600 =5/12
