The pair of simultaneous linear equations for "The price of a book is 50 rupees more than a notebook and their total price is Rs. 115." is as follows?
- x − y = 50, x + y = 115
- x + y = 50, x − y = 115
- x + y = 165, x − y = 50
- None of these
Explanation
Let book price = x, notebook price = y
Book is 50 rupees more than notebook: x = y + 50 => x - y = 50
Total price is 115: x + y = 115
x − y = 50, x + y = 115
