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.
Answer:
15:7
Step-by-step explanation:
We will first the answer by dividing 180 rupees by 1 dozen. Its answer will be the first part of the ratio. Let's call the quotient x. Then, we will divide rupees 56 by 8. Let's call this quotient y. So, the ratio is x:y.
Rs 180/ 1 dozen = Rs 180/12 = Rs 15
Rs 56/8 = Rs 7
Therefore, ratio is 15:7
