The extra 50 member did not drink coffee and tea.

Answer 2

Answer:

20 is it's right answer...

Step-by-step explanation:

60 drinking tea and 50 drinking coffee

sub. 30(coffee drinking students) from 60

= 30

sub. 30(tea drinking students) from 50

= 20

It means 30 students are those who drink only tea 20 students are those who drink coffee only and 30 students and those who drink both

= 100 - ( 30 + 30 + 20 )

= 100 - 80

= 20

therefore there 20 total students are those who drink nothing
