(2) 820
(3) 1,680
(4) 2,080
(5) 16,800​

Answer 1

Explanation:

• Total number of albums = 10 albums
  `\;`
• Number of pages in each album = 42 pages
• Stamps fit on 1 page = 40 stamps

As total number of pages in each album is 42 pages, so

➝ Total number of pages in 10 albums = (42 × 10) pages

➝ Total number of pages in 10 albums = 420 pages

Now, as the number of stamps fit on 1 page is 40 stamps, so

➝ Stamps fit on 420 pages = (420 × 40) stamps

➝ Stamps fit on 420 pages = 16,800 stamps

Therefore, 16,800 stamps are in the total collection.
