Question

find the ratio of the cost of pen to the cost of pencil if the cost of a dozen of pencil is 18 and 8 pens 104​

Answer 1

Answer:

Ratio = 9:1

Step-by-step explanation:

Dozen = 12

12 pencils for Rs. 18

1 pencil for Rs. x

x = 18/12 = 3/2

One pencil costs Rs. 3/2

8 pens for Rs. 104

1 pen for Rs. y

y = 104/8 = 27/2

One pen costs Rs. 27/2

Ratio of Cost of pen to the Cost of pencil i.e.

Cost of pen/Cost of pencil

= (27/2) / (3/2)

= (27/2) x (2/3)

= 9/1

Ratio = 9:1
