Answer 2

Given: Cost of notebook is Rs. 5 more than the cost of pen

           Sum of cost of 4 pens and 5 notebooks = Rs. 88

To find: Cost of one pen and one notebook.

Step-by-step explanation:

Let the cost of pen be Rs. x  .

Then, cost of notebook = Rs.(x+5)

According to question,

4x + 5(x+5) = Rs.88

4x + 5x +25 = 88

       9x+ 25 = 88

               9x = 88-25

                9x = 63

                   x = 63/9

                     x = 7

∴ Cost of pen = Rs. 7

  Cost of notebook = Rs. 12

Answer: Cost of one pen and one notebook is Rs.7 and Rs. 12 respectively.
