The value of the pressure is 1 when the value of volume is 10 liters, the correct option is D.
<h3>What is the pressure?</h3>
Pressure is defined as the physical force exerted on an object.
The force applied is perpendicular to the surface of objects per unit area.
Given
The equation is

Where the v is the volume and p is the pressure.
The value of p when the value of volume v is 10 liters is;

Hence, the value of the pressure is 1.

Answer:
5. Profit of Rs 1 per lemon
6. Rs 20
Step-by-step explanation:
5. Buy Rs 60 per 12 lemons = Rs 5 per lemon
Sell Rs 30 per 5 lemons = Rs 6 per lemon
Profit Rs 1 per lemon
6. Sell Rs 2500 per 100 pens = Rs 25 per pen
Profit per pen is 20% = (20/100)25 = 5
Cost price of a pen = 25 - 5 = 20
The sequence that represents a geometric sequence can be seen in the 1st option and the 4th option in the image attached.
<h3>What is a geometric sequence?</h3>
A geometric sequence is a set of integers that follows a pattern in which the following term is determined by multiplying the previous one by a factor known as the common ratio (r).
or 



From the options given, the options that have geometric sequences are:
r = (3/8)/(3/16) = (3/4)/(3/8) = 2 (proves that it is a geometric sequence)
- 3, 9, 27, 81
- r = 9/3 = 27/9 = 3 (proves that it is a geometric sequence)
