Q1:

The internal resistance of a 30,000 ohm/volt voltmeter set on its 50 V range is

A 15,000 

B 150,000 

C 1,500,000 

D 15,000,000 

ANS:C - 1,500,000 

The voltmeter has an internal resistance of 30,000 ohm/volt.
That is for 1volt the resistance is 30,000 ohm.

Therefore,
For 50v the resistance.
50*30, 000 :-1,500,000Ω.
