70% to pass

If the GMT is 1500, the time at 75°E longitude is _______________.

A 1000
B 1500
C 1700
D 2000
AI Explanation

The correct answer is D) 2000. The reason for this is that when the GMT (Greenwich Mean Time) is 1500, the time at 75°E longitude is 2000. This is because the time zone difference between Greenwich and 75°E longitude is 5 hours, with the eastern longitude being 5 hours ahead of GMT. The other options are incorrect because A) 1000 is 5 hours behind GMT, B) 1500 is the same as GMT, and C) 1700 is 2 hours ahead of GMT, which does not match the time zone difference of 5 hours for 75°E longitude.
