Answer:
28
Step-by-step explanation:
There are 8 women in the party, all of different heights, and only the women only shake hands with people shorter than them.
therefore, the tallest woman does not get any handshakes.
so,
a = 0
n = 8
d = 1
the total no. of handshakes = Sn
Sn = n/2 (2a + (n-1) d )
= 8/2 (2*0 + (8-1) * 1)
= 4 ( 0 + 7 )
= 4 (7)
= 28
therefore, a total of 28 handshakes will take place.
