Question

b. face east and make one - fourth of a revolution clockwise.
​

Answer 1

Let North be - 12'o clock

Let South be - 6'o clock

Let West be - 9'o clock

Let East be - 3'o clock

When we take a clockwise direction from east, we face towards south. (Imagine you are a clock)

Then, taking one- fourth that is three-twelveth clockwise turning is as turning from 3'o clock to 3 hours that is 6'o clock which is South direction
