Answer:
20000
Step-by-step explanation:
115%-> 23000
100%->20000
Let the Price of 1 magzine = x
Margin on 1 Magzine = (10%)(x) rupees = 0.1 x
Margin on 42 Magzines = 42(0.1 x) = 4.2 x
Also
Let the Price of 1 books = y
Margin on 1 Book = (15%)(y) rupees = 0.15 y
Margin on 14 Books = 14(0.15 x) = 2.1 y
Basic Pay of Adam = 200
Amount that Adam earned last week = 200 + 4.2 x + 2.1 y

The correct option is: A. 80 cm³
Explanation
Diameter of the coin,
cm.
So, the radius,
cm.
As the coin is circular, so..
Area of each circular surface,
cm²
Now for finding the amount of plastic for making each coin, we will find the Volume of each coin first.
As the thickness (
) of the coin is 0.5 cm, so Volume of each coin,

As you need to make a batch of 50 coins, so the total volume of 50 coins
[Rounded up to the nearest multiple of 10 cm³]
So, the amount of plastic you will need for making a batch of 50 coins is 80 cubic centimeter.
