A clock behaves abnormally. After it is set, for the 1st hour it functions properly and after that its hour hand starts functioning like minute hand and minute hand starts functioning like hour hand for next 2 hours. After that once again the clock starts functioning properly for 1 hour and after 1 hour faces the same problem. If this process continues then what will be the time shown by the clock, if the clock is set at 12 midnight and the time shown by the correct clock is 7 a.m. on the same day?
