Let x = # of hot dogs that Jim ate
Jim ate four times as many hot dogs as Leon
In other words, Leon ate 1/4 as many hot dogs as Jim ate
So, x/4 = # of hot dogs that Leon ate
Jim ate half as many hot dogs as Billy
In other words, Billy ate twice as many hot dogs as Jim ate
So, 2x = # of hot dogs that Billy ate
In TOTAL they ate 78 hot dogs
So, x + x/4 + 2x = 78
Solve to get: x = 24
So...
Jim ate 24 hot dogs
Leon ate 6 hot dogs
Billy ate 48 hot dogs
How many more hot dogs did Billy eat than Leon?
48 - 6 = 42 = D

Total \(= L + B + J = 78\)
\(J = 4L\)
\(\frac{J}{L} = \frac{4}{1}\)
\(J = \frac{1}{2}B\)
\(\frac{J}{B} = \frac{1}{2}\)
Let us make Js equal;
\(\frac{J}{L} = \frac{4}{1}\), \(\frac{J}{B} = \frac{1}{2}\)
\(\frac{J}{L} = \frac{4}{1}\), \(\frac{J}{B} = \frac{1(4)}{2(4)}\)
\(\frac{J}{L} = \frac{4}{1}\), \(\frac{J}{B} = \frac{4}{8}\)
Therefore, \(J : L : B = 4 : 1 : 8\)
The question asks \(B - L = \frac{(8 - 1)}{(4 + 1 + 8)}(78) = 42\)
Hence, option D
