Answer:
first server served = 48 guests
second server served = 16 guests
third server served = 96 guests
Step-by-step explanation:
total guests = 160
let second server served = x guests
as per given:
first server served = 3x guests
third server served = 2(3x) = 6x guests
i.e.
x + 3x + 6x = 160
10x = 160
x = 160/10 = 16
thus,
first server served = 3x = 3(16) = 48 guests
second server served = x = 16 guests
third server served = 6x = 6(16) = 96 guests
