Answer 2

Answer:

here your answer is Rs. 35/2.

Step-by-step explanation:

Cost of each pencil = Rs. 2 1/2

So, cost of 7 pencils = Rs. 2 1/2 * 7

                                  = Rs. [(2 * 2 + 1)/2] * 7

                                  = Rs. 5/2 * 7

                                  = Rs. 35/2
