F=1.8C+32, where F is temperature in fahrenheits, C is temperature in celsius.
If fahrenheit temperature is twice as that of celsius, then F=2C.
So, 2C=1.8C+32
=>0.2C=32
=>C=32/0.2 = 160
So, required temperature = 160 deg. celsius = 160+273 = 433 K (option c)

C++ Code needed Celsius Temperature Table The formula for converting a temperature from Fahrenheit to Celsius is C =5/9(F -32) where F is the Fahrenheit temperature and C is the Celsius temperature. Write a function named celsius that accepts a Fahrenheit temperature as an argument. The function should return the temperature, converted to Celsius. Demonstrate the function by calling it in a loop that displays a table of the Fahrenheit temperatures 0 through 20 and their Celsius equivalents.
