A family of four-grandfather, father, son and daughter-are caught in a
heavy rain and are stranded at a bus stop close to their home. However
they have only one umbrella with them.
The umbrella can take a maximum of two people without either of them
getting wet. The four members of the family take different times to walk
from bus stop to home. The grandfather is slowest of all, taking 10 minutes,
followed by the father who takes 5 minutes. The son takes 2 minutes,
while the daughter takes only a minute. What is the minimum total time
(in minutes) for all four members of the family to reach home without any
of them getting wet?

Answer:
17
Step-by-step explanation:
- Son and Daughter go - +2 minutes [Daughter comes back(+1 min)]
- GF and Father go - +10 minutes [Son comes back(+2mins) ]
- Son and Daughter go - +2 minutes
So, the total time would be 2+1+10+2+2 = 17 minutes.
