\((x+y)_{max.} = 2+2 = 4\)

\((s+t)_{min.} = 0.4+0.4 = 0.8\)

largest possible value of (x+y)/(s+t) = \((x+y)_{max.} / (s+t)_{min.}\)

largest possible value of (x+y)/(s+t) = \(4/0.8 = 5\)

Answer: option D


Just and advise: Don't refer to barrons as it's a pathetic source to refer to and has multiple mistakes in the questions.

I hope this helps!!!
