if voltmeter has very high resistance then why its resistance is not included while solving for the net R?

Answer:
:) it seems like you are pretty confused in this
Resistance is the opposition given the electric current.
Voltmeter should have a high resistance dosent mean that voltmeter have its own resistance but,
voltmeter measures the voltage difference between two different points (say, on different sides of a resistor),
but it should not change the amount of current going through the element between those two points. So, it should have very high resistance so that it doesn't "draw" current through it..
and also
high resistance doesnt mean that it has its own resistance but many resistors are connected across it (u know the reason now)
