Question

Need help with this question my answer was number 3 but I not for sure that the correct answer.

Answer 1

Given that;

A stamp collection consists of 10 albums, each containing 42 pages.

The total number of pages in the 10 albums is

`=10*42=420\text{ pages}`

If 40 stamps fits on a page, the number of stamps in the total collection will be

`=420*40=16800`

Hence, the answer is 16,800 (Option 5)
