1. The problem statement, all variables and given/known data I visited my friends home during my holidays.Our schedule went like this. We went for a walk in morning and played badminton in the evening. However due to the tiring nature of these, we did only 1 of them each day, i.e either walked or played Badminton. On some days we did neither!On 11 mornings we did nothing, 10 evenings we did nothing, we walked or played Badminton on a total of 11days. How long did i stay@ my friends place? 2. Relevant equations How long did i stay @ my friends place? 3. The attempt at a solution 1 activity each day. total activities=11 events=11 days (morning+evening) 11 mornings+10 eveings did nothing= 10 days + 1 morning. so, i guess.. 11+11=22 days?? pls confirm the same.
