12. Cost of a dozen pens is 180 and cost of 8 ball pens is 56. Find the ratio of the cost
of a pen to the cost of a ball pen.​

Answer 1

Answer:

First, let's find the cost of a pen.

12 pens = 180 rupees

1 pen = 180 ÷ 12

         = 15 rupees

Now, let's find the cost of a ball pen.

8 ball pens = 56 rupees

1 ball pen = 56 ÷ 8

                = 7 rupees

Therefore, the ratio of the cost of a pen to the cost of a ball pen is 15:7.
