2005 PMWC Problems/Problem I14

Solution

From the given, we have the equations

\[3g = 6b \Longrightarrow g = 2b\] \[2y = 5b \Longrightarrow y = \frac{5}{2}b\] \[4w = 6b \Longrightarrow w = \frac{3}{2}b\]

Substuting gives us $4g + 2y + 2w = 4(2b) + 2\left(\frac{5}{2}b\right) + 2\left(\frac{3}{2}b\right) = 16b$, and our answer is 16.
