Question

ball pen rs 57.60 per dozen and pencil cost rs 84 per scare find the ratio of the price of a pencil to that of a ball pen​

Answer 1

Answer:

That's not scare

it's SCORE

The ratio of a pencil ✏ to that of a pen ✒ is 7 : 8

One score = 20 pencils

So we get 20 ✏s for 84 rupees

cost of one ✏ is 84/20 = 4.2 rupees

We get 12 pens for 57.60 rupees

so cost of one ✒ is 57.60/12 = 4.8 rupees

so the ratio goes like this

4.2 / 4.8 = 7/8

I hope u got ur answer my dear friend ✌✌

Answer 2

Solution:

Given:

⇒ Cost of ball pen = 57.60 per dozen

⇒ Cost of pencil = 84 per scare

To Find:

⇒ Ratio of the price of pencil and ball pen.

As we know,

⇒ 1 Dozen = 12

⇒ 1 Score = 20

So, cost of 1 ball pen = 57.60/12

⇒ cost of 1 pencil = 84/20

Now, ratio of the price of a pencil to that of a ball pen​ is:

⇒ 57.60/12:84/20

⇒ 4.8:4.2

⇒ 4.8/10:4.2/10

⇒ 48:42

⇒ 8:7

Hence, the price of a pencil to that of a ball pen​ is 8:7.
