JEE Main 2019 (Online) 11th January Evening Slot Physics - Heat and Thermodynamics Question 327 English Explanation

$$ \Rightarrow $$   ToC = $${{{x_0}} \over 6}$$ & $$\left( {{x_0} - {{{x_0}} \over 3}} \right)$$ = (100 $$-$$ 0oC)

x0 = $${{300} \over 2}$$

$$ \Rightarrow $$  ToC = $${{150} \over 6}$$ = 25oC
