Holiday Trip
Submitted by Brijesh Dave
A group of friends and I went on a holiday trip to a hill station.
It rained for 13 days.
But when it rained in the morning, the afternoon was lovely.
And when it rained in the afternoon, the day was preceded by a clear morning.
Altogether there were 11 very nice mornings and 12 very nice afternoons.
How many days did our holiday last?
