Assume that Pinky is surrounded by 3a and 5a people, respectively.
A total of \(3a + 5a + 1\) (including pinky) equals
\(8a + 1\);
\(8a + 1 < 300; 8a < 299. \)
\(⇒ a < 37.375.\)
A can only take a maximum of 37 values.
Assuming \(3a = 3\times 37 = 111\),
the greatest number of people that might possibly be in front of Pinky is 3.
