Answer 1

pen's cost is more by rs.2.4

Answer 2

Answer:

Pen costs Rs.2.50 more than cost of one pencil.

Step-by-step explanation:

Cost of a pen = 20/3

Cost of a pencil = 25/6

Lets make their denominator equal, for which we can multiply cost of pen by 2/2, after that

Cost of pen is 40/6 and cost of pencil is 25/6

We can see

6 Parts of 40 > 6 parts of 25

∴ Cost of pen is more than cost of pencil.

Difference between cost = cost of pen - cost of pencil

                                          = (40/6) - (25/6)

                                          = 15/6 or or 2.50

∴ One pen costs Rs.2.50 more than cost of one pencil
