on increasing the number of lines in a page by 110 , they become 240 . what is the % of increase in the no . of lines in the page ?
"explanation : number of pages increased = 110 now , the number of pages of book = 240 number of pages of the books before increase = 240 – 110 = 130 % increase in the number of pages in the book = 110 / 130 x 100 % = 84.6 % e"
subtract(multiply(divide(240, subtract(240, 110)), const_100), const_100)
