Answer:
North West
Step-by-step explanation:
Let say North = j East = i
South = -j & west = -i
Ant moves 4m eastward = 4 i m
then turns right => South
moves 7 m forward
=> -7j
Turns right => West
moves 3m
=> -3i
4i -7j - 3i
= i - 7j
Ant is South East
to go back to origin ant has to move 0 - ( i - 7j)
= -i +7j
Ant has to move North West
