Answer:
Let C and A denotes the percentage of people likes cheese and apples respectively.
Given, n(C)=63,n(A)=76 and n(C∩A)=x.
We know that,
n(C∪A)=n(C)+n(A)−n(C∩A)
⇒n(C∪A)=63+76−x
⇒x=139−n(C∪A)
Now, n(C∪A)≤100
⇒139−n(C∪A)≥139−100=39
⇒x≥39
Also, n(C∩A)≤n(C) and n(C∩A)≤n(A)
⇒x≤63
∴39≤x≤63.
I hope it helps you...
