Answer :
To find the cost of one book when the total cost of 4 books is Rs. 200, we can follow these steps:
1. Identify the total cost and the number of books: We are given that the total cost for 4 books is Rs. 200.
2. Determine what we need to find: We need to find the cost of one book.
3. Set up the equation:
- Let the cost of one book be `x`.
- Since there are 4 books, the total cost is represented by `4 x`.
4. Use the given total cost to form the equation:
- Given total cost = Rs. 200
- Therefore, the equation becomes: `4 x = 200`.
5. Solve for `x`:
- To find the value of `x`, we divide both sides of the equation by 4:
[tex]\[ x = \frac{200}{4} \][/tex]
6. Calculate the division:
- [tex]\( \frac{200}{4} = 50 \)[/tex].
Hence, the cost of one book is Rs. 50.
