Answer 2

Given: Total  money Bilal paid for novel and notebook = Rs.500

             Cost of novel is Rs. 80 more than twice the cost of notebook.

To find: Cost of novel

Step-by-step explanation:

Let the cost of notebook be Rs. x

Then, cost of novel = Rs.(80+2x)

According to question,

cost of notebook + cost of notebook = Rs.500

        x + 80 + 2x = 500

                  80 + 3x = 500

                          3x = 500 - 80

                            x = 420/3

                            x = 140

∴ Cost of notebook = Rs. 140

   Cost of novel = Rs.(80+2x)

                           = Rs.(80+2×140)

                            = Rs. 360

Answer: Cost of novel = Rs. 360
