A) \[{{31}^{\circ }}\]
B) \[{{51}^{\circ }}\]
C) \[{{20}^{\circ }}\]
D) none of these
Correct Answer: A
Solution :
\[{{100}^{\circ }}C={{150}^{\circ }}\] of the thermometer |
\[\therefore \]\[{{1}^{\circ }}C={{1.5}^{\circ }}\] of the thermometer |
Or \[{{34}^{\circ }}C={{51}^{\circ }}\] of the thermometer |
\[\therefore \] thermometer will read \[-{{20}^{\circ }}+{{51}^{\circ }}={{31}^{\circ }}\]of the thermometer |
