On a shelf, books with green cover and that with brown cover are in the ratio 2:3.
If there are 25 books on the shelf. find the number of books with green cover and
the number of books with brown cover?
Answers
Given :
- Ratio of books with green cover = 2:3
- Total number of books on the shelf = 25 books.
To Find :
- Number of books with green cover and with brown cover.
Calculations :
Let us consider the number of books with green cover as 2x answer the number of books with brown cover as 3x.
And,
- Given that, total number of books is 25 books.
So, firstly let's calculate the value of x,
⇒ 2x + 3x = 25
⇒ 5x = 25
⇒ x = 25/5
⇒ x = 5
- Hence, the value of x is 5.
Now, calculating the total number of books with green cover and with brown cover.
Total number of books with green cover :
It's given that, ratio of books with green cover is 2:3.
So,
→ 2x = 2 × 5 = 10 books
Therefore, total number of books with green cover is 10 books.
Total number of books with brown cover :
→ 3x = 3 × 5 = 15 books.
Therefore, total number of books with brown cover is 15 books.
Henceforth,
- Total number of books with green cover = 10 books.
- Total number of books with brown cover = 15 books.
Verification :
Here, the total number of books is 25 books [given]. So, let's check.
⇒ 10 + 15 = 25 books
⇒ 25 = 25 books
⇒ L.H.S = R.H.S
Hence, verified!
