Question

The cost of 3 notebooks and 5 similar pens is Rs. 460. If the notebook cost is Rs. 20 more than the pen, then find the cost of each.​

Answer 1

The cost of each notebook is Rs. 70, and the cost of each pen is Rs. 50.

Given:

The cost of 3 notebooks and 5 similar pens is Rs. 460.  

The notebook cost Rs. 20 more than the pen

To find:

The cost of each

Solution:

Let's assume that the cost of one pen is x.

Then, the cost of one notebook =  x + 20

According to the problem,

The cost of 3 notebooks and 5 similar pens is Rs. 460. So,  

=> 3(x + 20) + 5x = 460

=> 3x + 60 + 5x = 460

=> 8x + 60 = 460

=> 8x = 400

=> x = 50

So, the cost of one pen is Rs. 50, and the cost of one notebook is Rs. 70  

Therefore,

The cost of each notebook is Rs. 70, and the cost of each pen is Rs. 50.
