Ohm's Law

Question-base...

Question

Question-based on practicals:
While experimentally verifying Ohm's Law, a student observed that the pointer of the voltmeter coincide with the 15th division when the voltmeter has a least count of 0.05V. Find the observed reading of the voltmeter. Answer with full explanations. (2 marks)
I am not able to solve this!!
