Answer

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

\frac{120}{5}

y = 

y = 24

Substituting y=24 in any of the equations, we get

x = 24 + 5

x = 29

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

Thus, the

You can also verify this answer by substituting the values of x and y as follows:
