I think it's 64. Not positive, but pretty sure it is.
Please upload the question and i will work it out, have a lovely day!
Ok, so 120 pages plus the 60% of the book she has left to read will give the total number of pages.
That means that 120 pages is 40% of the book.
Make a proportion
120/40% = x/60%
72 = .4 x
x = 180 pages
The answer would be n = 1
