Problem: on increasing the number of lines in a page by 100 , they become 240 . what is the % of increase in the no . of lines in the page ?
Rationale: "explanation : number of pages increased = 100 now , the number of pages of book = 240 number of pages of the books before increase = 240 – 100 = 140 % increase in the number of pages in the book = 100 / 140 x 100 % = 71.4 % d"
annotated_formula: subtract(multiply(divide(240, subtract(240, 100)), const_100), const_100)
