Newton's law of cooling

VITEEE Tutorials › Thermal physics questions › Newton's law of cooling

A hot body placed in air is cooled down according to newton's law. The rate of decrease of temperature being K times the temperature difference from the surrounding. Starting from t=0, find the time in which the body will lose half the maximum temperature it can lose.
I got the answer as ln 2/K, but the answer given is ln2/3K
