A Carnot engine operating between two reservoirs has efficiency $\displaystyle \frac{1}{3}$. When the temperature of cold reservoir raised by $\displaystyle x$, its efficiency decreases to $\displaystyle \frac{1}{6}$. The value of $\displaystyle x$, if the temperature of hot reservoir is $\displaystyle 99$°C, will be :
