The hands shakes took place in class is15

Hey mate here is your answer

Total number of students=15

So if one student will go and give handshake he will give to 14 students only because who is giving the handshake is one student so apart from one student there are 14 students.

So15×14=210

Therefore 210 handshakes took place the class
