In a school library there are 35% English books,25% maths books and the remaining 250 books are on general subjects. How many books are there in the library?
35+25 = 60%
so, 40% are general
.40x = 250
x = ?
To find the total number of books in the library, we need to add up the number of books in each category (English, math, general subjects).
Let's start with the information given:
- 35% of the books are English books
- 25% of the books are math books
- The remaining 250 books are on general subjects.
To calculate the number of English books, we need to find 35% of the total number of books.
35% of the total number of books = (35/100) * total number of books
Similarly, the number of math books can be calculated as 25% of the total number of books:
25% of the total number of books = (25/100) * total number of books
The number of books on general subjects is given as 250.
To find the total number of books, we need to add up these three quantities:
Total number of books = number of English books + number of math books + number of general subject books
So the equation becomes:
Total number of books = (35/100) * total number of books + (25/100) * total number of books + 250
We can simplify this equation to solve for the total number of books:
Total number of books = 0.35 * total number of books + 0.25 * total number of books + 250
Now, we can solve this equation to find the total number of books.
