Question

sara read 2/5th of a book on the first day.she read 1/3rd more on the second day than she read on the first day. 15 pages were left for the third day.the number of pages in the book is

Answer 1

Let there be x pages in books 

Then, Pages read on first day = 2x/5
Pages read on second day = 2x/5 + 2x*1/5*3
                                            = 2x/5 + 2x/15
                                            = 6x+2x/15 = 8x/15

Pages left = 15

So, Total pages, x = 2x/5 + 8x/15 + 15
                        x =    6x+8x+225/15
         so, 15x-14x = 225
       So, Total pages ,x = 225
