The temperature inside the copper rod varies linearly with the distance from the hot end of the rod. This means that we can find the temperature at 23 cm (let's call it 'point A') from the cool end by solving a linear proportion.
The temperature difference between the two ends of the rod is

and this corresponds to a length of 81 cm. Therefore, we can write:

from which we find

This is not the final answer actually; this is the temperature difference between the cool end and point A. So, the temperature at point A is

Based on the information given, it can be noted that the bat was either shorter or longer than what he expected.
From the information given, it was stated that Raghu wants a cricket bat to be made by a carpenter and he tells the carpenter that the length of the bat should be 7 hand spans. 
Since he got disappointed when he collected the bat, the reason for this will be because the bat was either shorter or longer than what he requested.
