TRUE BEARING = MAGNETIC BEARING - MAGNECTIC DEC.
TB = 32' - 10'15' = 21'45'.
TB = 32' - 10'15' = 21'45'.

60 - 15 = 45 degree.
31 - 10 = 21 degree.
Total = 21 degree 45 minute.
31 - 10 = 21 degree.
Total = 21 degree 45 minute.

Answer should be B.
True bearing=magnetic bearing+magnetic declination.
True bearing=magnetic bearing+magnetic declination.

True bearing=MB- Declination.
TB=32°-10°15
= 21°45.
TB=32°-10°15
= 21°45.

The Answer is A) declination is westward ie, negative.

Magnetic bearing toward West is -ve so just subtract.

@Amit.
TB = MB - MD if declination is westward.
TB = MB - MD if declination is westward.

@Anmol.
60-15 = 45 minutes? Explain it.
60-15 = 45 minutes? Explain it.
