Solution
Longitude of Delhi = 77°E
Longitude of Tokyo = 139°E
The difference per degree = 139° – 77° = 62°
Difference of time per degree = 4 minutes
Difference between the time of Delhi and Tokyo = 4 × 62 = 248 minutes = 4 hours 8 minutes
Since Delhi lies west of Tokyo we shall subtract 4 hours 8 minutes from Tokyo time. Hence local time at Delhi is 10.52 a.m.
