A Fahrenheat thermometer reads 113F while a faulty celsius thermometer reads
44°C. The correction to be applied to the celsius thermometer is
1)-1°C
2)+1°C
3142°C
4)-2°F​

Answer 1

Temperature in Fahrenheit = 113°F (given)

Temperature given by the faulty thermometer = 44°C

Now, the correct temperature in Celsius
$= \frac{(113 - 32 )\times5 }{9} \\ = \frac{81 \times 5}{9 } \\ = 45 \degree$

Therefore, the correction to be applied
= 45°C – 44°C
= 1°C

Hence, the correction to be applied is +1°C.
