The random errors associated with the measurement of P and Q are 10% and 2%, respectively. What is the maximum percentage random error in P/Q?
Solution:
We are given:
When quantities are divided or multiplied, the percentage errors are added.
So,
Maximum percentage error in (P ÷ Q) = Error in P + Error in Q
= 10% + 2% = 12%
Final Answer: (A) 12.0
