Friday night's attendance was 200.

Attendance increased from Friday night to Saturday night by 16 people

16+f=1.08×f
F=200 and S=216

Answer should be D
for statement #2
Let S = people on saturday and
F = People on Friday
As per Statement #2 (S-F) = 16
and as per the question an increase of 8% in attendance when compared to Friday
Hence (S-F)/F * 100 = 8
Calculating F by substituting (S-F) = 16 gives us the value of F (200) essentialy recreating the Statement #1
