Question

the price of 3 notebook and 2 text books in Rupees 135 but a notebook cost 5 rupees more than the textbook find the cost of the book the notebook and text book.

Answer 1

Let the cost of each notebook be 'x' and cost of each textbook be 'y'.

From the data given in the question, we can write the following equation:
3x + 2y = 135

However, it is given that a notebook costs Rs. 5 more than the textbook. Thus,
x = y + 5

Substituting this in the earlier equation, we get
3 (y+5) + 2y = 135
3y + 15 + 2y = 135
5y = 135 - 15
5y = 120
y = $\frac{120}{5}$
y = 24

Substituting y=24 in any of the equations, we get
x = 24 + 5
x = 29

Thus, the cost of each notebook is Rs. 29 and the cost of each textbook is Rs. 24

You can also verify this answer by substituting the values of x and y as follows:
3(29) + 2 (24) = 135
87 + 48 = 135
135 = 135

Hence our solution is correct.
