Two surveys were published by two separate marketing organisations on consumption of tea and coffee in Drinkville.

 

The first organisation interviewed 100 people and the results showed that

78 of them drink coffee 

71 of them drink tea 

48 of them drink both coffee and tea.

 

The second organisation interviewed 115 people and the results showed that

91 of them drink coffee 

82 of them drink tea 

58 of them drink both coffee and tea  

 

Which of these two results are not correct? Justify your answer
