Question

On the "New" temperature scale, water boils at $500$ and freezes at $300$ understand conditions.
${38}^{o}C$ corresponds to what temperature on the "New" scale?

• A. $356$ New
• B. $338$ New
• C. $319$ New
• D. $438$ New
• E. $376$ New

Answer 1

The correct option is E $376$ New

We know that water boils at ${100}^{o}C$ and freeze at $0^{o}C$. So the relation between new scale and Celsius scale will be - $\frac{N-300}{200}=\frac{C-0}{100}$

When, $C=38,N=2C+300=2\left(38\right)+300=376$
