It was vacation time, and so I decided to visit my cousin's home. In the mornings, we both would go for a jog. The evenings were spent on the tennis court. Tiring as these activities were, we could manage only one per day, i.e., either we went for a jog or played tennis each day. There were days when we felt lazy and stayed home all day long.
Now, there were 9 mornings when we did nothing, 13 evenings when we stayed at home, and a total of 12 days when we jogged or played tennis. For how many days did I stay at my cousin's place?

x- go for jog
y- play tennis
z- stay home
Now
y+z=9
x+z=13
x+y=12
On solving,
x=8
y=4
z=5
Total = 17 days. Ans

Anish is correct:
5 days when they did nothing.
Jogged in the morning on 8 days, and played tennis in the evening on 4 occasions.
