Plastic is also a polymer like synthetic fibre.

There are two types of plastics: thermoplastics and thermosetting plastics.

• Thermoplastics
• Some plastic gets deformed easily on heating and can be bent easily are known as thermoplastics.
• Polythene and PVC are some examples of thermoplastics.
• Thermoplastics are used in the manufacturing of combs, toys, and various containers.
• Thermosetting plastics
• Some plastics, on the other hand,  which when moulded once, can not be softened by heating are known as thermosetting plastics.

Given:

Parts of water in the liquid = 3

Parts of medicine in the liquid = 7

Formula used:

Remaining value = Initial value ( 1 - fraction removed)

Calculation:

Initial value of medicine = 7/10

Remaining value of medicine = 1/2 (as water : medicine = 1 : 1)

So.

Remaining value = Initial value ( 1 - fraction removed)

⇒ 1/2 = 7/10 (1 - fraction removed) 

⇒ 5/7 = (1 - fraction removed)

⇒ fraction removed = 1 - 5/7 = (7 - 5)/7 = 2/7

∴ The correct answer is option (1).
