Question

The waiter places a bowl of soup in front of Lacy. In a counterclockwise direction, she passes the soup 90°. The person receiving the soup passes it 30°. After the two passes, the soup is in front of which person ?○ Haifa○darcy○garret○igor

Answer 1

Notice that we have 12 people evenly distributed in a round table (360°).

This way, each person would be

$\frac{360}{12}=30$

30° from each other.

After the two passes, the soup would have moved 120°, meaning that

$\frac{120}{30}=4$

It would have moved 4 places.

Now, the person sitting 4 places away from Lacy, if the soup is passed counterclockwise, is Haifa

Therefore, the soup would be in front of Haifa.
