Answer:
500
Step-by-step explanation:
n(t)=4000
n(c)=4500
n(tea only )= 4000-x
n(coffee only )= 4500-x
n(coffee and tea )= x
note...using Venn diagram ..all together must add up to 9000
(4000-x)+(4500-x) +x = 9000
..............
...........collect like terms
9500-9000 = x
x = 500
No of people likes tea = 4000
No of people like coffee = 4500
Total = 8500
No of people don't like tea and coffee = 2500
No of people like tea and coffee = 8500 - 2500 = 6000
5522
2,761 times 2 = 5522
