Answer:
every 1° is equal to 4 minutes.
If it is on west of greenwich median than substract the calculated time from actual time of GMT and if it is on east than add.
69°E = 69×4 = 276 minutes i.e 4 hours 36 minutes.
time on greewich is 12:00 . so, time on 69°E is
12 +4 hr 36 min = 16:36
similarly in case of 30°west we have to substract the time i.e
12 - 2 hrs = 10:00
and for 12°E again add
12+48 min = 12:48
Hope this was helpful.
