Question

If temperature of an object is $140{}^{\circ }F$ , then its temperature in centigrade is

• A. $105^{\circ }C$
• B. $32^{\circ }C$
• C. $140^{\circ }C$
• D. $60^{\circ }C$

Answer 1

Answer: (D)

Relation between ${}^{\circ }C$ and ${}^{\circ }F$ ,
$\frac{C}{5}=\frac{F-32}{9}$
$\Rightarrow \frac{C}{5}=\frac{140-32}{9}$
$\Rightarrow C=60^{\circ }C$
