Question

One-fifth of the temperature (C) in centigarde of body increased by 10${}^o$ is equal to its temperature in Fahrenheit (F). Find F when C = 20${}^o$.

• A. $13$ degrees
• B. $14$ degrees
• C. $15$ degrees
• D. $16$ degrees

Answer 1

The correct option is D $16$ degrees

From the given statement, we can write the formula as
$F=\frac{1}{5}C+10$

Substituting C = 20 in the above formula, we get

$F=\frac{1}{5}20+12$

$F=4+12$

$F=16$ degrees

So, option D is correct.
