A) \[-{{42}^{o}}\]
B) \[-{{72}^{o}}\]
C) \[+\,{{12}^{o}}\]
D) \[-{{40}^{o}}\]
Correct Answer: C
Solution :
We are given the relation between the temperature scales A and B as \[\frac{A-42}{110}=\frac{B-72}{220},\]so for the two scales to 110 220 have the same reading A = B and so \[\frac{A-42}{110}=\frac{A-72}{220},\]which yields A = 12.You need to login to perform this action.
