Answer :
Final answer:
52% of a 375-page book remains to be read when 12/25th part of it has been already read. We reach this conclusion by first calculating the number of pages read, finding the number of pages remaining, and then calculating the percentage using part/whole*100 formula.
Explanation:
To solve this problem, we first need to find out how many pages have been read. If you've read 12/25 of a 375-page book, you've read (12/25)*375 = 180 pages.
Then, we find the remaining pages by subtracting the pages read from the total. So, 375 - 180 = 195 pages are remaining.
Next, we calculate the percentage of the pages remaining. Percentage is calculated by the formula (part/whole)x100%, where the part is the number of pages remaining, and the whole is the total number of pages in the book.
So, (195/375)x100% = 52%, thus, the percentage of pages remaining to be read is 52%. Therefore the answer is b) 52%.
