Q. Hemamalini was enjoying her vacation at her Cousin's home. In the mornings, she used to go for a jogging with her cousin. The evenings were spent on tennis court in nearly sports club. Since the activities of jogging and playing tennis were tiring, they could manage only one per day, i.e., either they went for a jog or played tennis each day. There were days when they felt lazy and stayed home all day long. For every four days they when for jog on first day, went for walk on the second day, did nothing for the third day and went for walk on the fourth day. This cycle continued. In total if they had played tennis for 30 days, how many total number of days Hema stayed in her Cousin's home.

Option
(a)15
(b) 14
(c) 18
(d) 60
(e) 15

• This is a very simple question. (Plenty of data is given just to confuse readers.)
  In every 4 days Hema and Cousin play tennis for 2 days. Since total number of days of playing tennis is 30, total days of stay can be calculated as follows
  
  Tennis Days Stay Days
  2 4
  30 ?
  Total number of days of stay = 30 x 4/2 = 60 days.

• In every 4 days they played tennis as 2 days, thus for playing 30 day tennis she have to lived with her for 60 days... so answer is 60.

• 1st day jog no tennis
  2nd day walk also tennis ---- total 15
  3rd day nothing
  4th day walk also tennis---- total 15
  thus she lived for 60 days (15*4)

• its very simple,
  1st day jogging
  2nd day walk,means no jogging,playing tennis
  3rd day did nothing
  4th day walk,means no jog,playing tennis
  so,played tennis 2days in evry 4 days
  played tennis 30 days in evry 30*(4/2)=60 days
  
  another solution
  he palyed tennis for 30 days,so according to the question its only possible when she stayed more than 30 days,so only option d,60days is possible.
