Answer 2

Answer:

there are 45 peoples

35 people like tea

so,(45-35)=10 people do not like tea

20 people like coffee

so, (45-20) =25 people do not like coffee

let x people like both tea and coffee

so,(35-x) people like only tea and

(20-x) people like only coffee

so, (35-x)+(20-x)+x=45

=> 35-x+20-x+x=45

=> -x=45-55

=> -x= -10

=> x=10

i)so 10 people like both tea and coffee

ii) 10 people do not like tea

iii) 25 people do not like coffee
