There are 28 biscuits in a small size.

There are 112 biscuits in a medium size.

There are 196 biscuits in a large size.

Step-by-step explanation:

Tin of biscuits come in three sizes:

Let S denote biscuits in small size.

Let M denote biscuits in medium size.

Let L denote biscuits in large size.

There are 28 biscuits in a small size and four times as many in the medium size.

Mathematically,

S = 28

M = 4S

Substitute S = 28

M = 4(28)

M = 112

In the large size there are seven times as many as in small size.

L = 7S

Substitute S = 28

L = 7(28)

L = 196

Therefore,

There are 28 biscuits in a small size.

There are 112 biscuits in a medium size.

There are 196 biscuits in a large size.
