W = Wanita
Pada pertemuan awal:
P : W = 5 : 3
Sehingga:
3P = 5W
P = 5/3 W
Beberapa waktu kemudian:
(P-2) : W = 3 : 2
Berlaku:
2(P-2) = 3W
2P - 4 = 3W
Substitusikan:
2(5/3)W - 4 = 3W
3W = 10/3 W - 4
10/3 W - 3W = 4
Didpat:
1/3 W = 4
W = 4 x 3
W = 12
Sementara itu:
P = 5/3 W
P = 5/3 x 12
P = 20
Maka, jumlah tamu awal:
n = P + W
n = 20 + 12
n = 32 orang
