# 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

**Solution:**

Cost of a dozen pens = ₹ 180

Thus, we can say that cost of 12 pens = ₹ 180 [Since, 1 dozen = 12]

Cost of 8 ball pens = ₹ 56

Now,

Cost of 1 pen = Cost of a dozen pens / 12

= ₹ 180 / 12

= ₹ 15

Cost of 1 ball pen = ₹ 56 / 8

= ₹ 7

The ratio of the cost of a pen to the cost of a ball pen

= Cost of 1 pen / Cost of 1 ball pen

= 15 / 7

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