5 People Grab Problem
A: We have 5 people, how are we going to take Grab from point Z to point Y? B: Hmm maybe one of us can take the train instead, while the other 4 takes the Grab? C: Why don't we book 2 Grabs instead? A: But that's going to be expensive.. Why don't we look at a 7 seater Grab instead, and compare the prices between that and taking 2 Grabs? B: Guys, I just thought of a better idea. A: ??? B: ??? C: Why don't we book a normal Grab.. Then we ask the Grab driver to take the train to point Y instead? So one of us would drive the Grab there and wait for the driver to arrive, before paying him and returning him the Grab car's keys?
