Solution

The correct option is C 32413 min. past 5
Rajesh went out between 5 and 6 and returned between 6 and 7.
He found that the hands of the clock had exactly changed places.
So, when he went out the hour-hand was between 5 and 6 and minute-hand was between 6 and 7.
And when he came back, the hour-hand was between 6 and 7 and minute-hand was between 5 and 6.
So, he went out between 5:305:35 and came back between 6:256:30.
Since the hands are exchanged he would have went around 5:32 and came back around 6:28.
There is a gap of 4 between 32 and 28.
Thus, he went out at 5 hour 32+413 min.
