A reading on Fahrenheit scale is . The same reading on celsius scale will be :
1.
40°C
2.
94°C
3.
93°C
4.
30°C
Hint: \(^\circ F = \frac{9}{5} t ^\circ C + 32\)
There are three common scales to measure temperature \(^\circ C\) (degree celcius), \(^\circ F\) (degree fahrenheit) and K (kelvin). The K is the SI unit.
The temperature on two cales are related to each other by the following relationship.
\(^\circ F = \frac{9}{5} t ^\circ C + 32\)
Putting the values in above equation
\(200 - 32 = \frac{9}{5} t ^\circ C\) \(\Rightarrow \frac{9}{5} t ^\circ C = 168\) \(\Rightarrow t^\circ C = \frac{168 \times 5}{9} = 93 . 3^ \circ C\)
