Question

Two temperature scales A and B are related by : A-42/110 B-72/220 At which temperature two scales have the same reading?​

Answer 1

Answer:

Since both the temperatures have the same reading, therefore we can use the result A=B. Using given relation in question, A−42110=B−72220. So, we get our answer as A=+12∘. So option (C) is correct.
