There are 3 clocks located at California, Berlin and Beijing respectively. If the hour hand of the clock at California is rotated by 270 degrees, then it will show same time as clock in Berlin. If the hour hand of clock in Berlin is rotated by 180 degrees, then it will show same time as clock in Beijing. If time at clock at Beijing is 8 : 30 PM what time is clock at California showing? Correct Answer 5 : 30 AM

Time difference when hour clock has swept 1 degree = 2 minutes

Time difference when hour clock has swept 270 degrees = 540 minutes = 9 hours

Time difference between California and Berlin = 9 hours

Time difference when hour clock has swept 180 degrees = 360 minutes = 6 hours

Time difference between Berlin and Beijing = 6 hours

Time difference between California and Beijing = 6 hours + 9 hours = 15 hours

Time at California = 20 : 30 – 15 = 5 : 30 AM

Hence, if time at clock at Beijing is 8 : 30 PM, clock at California show 5 : 30 AM.
