Question

Form the intersection for the following sets.

Answer 1

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

R={10,15,20}

and

S={20,25}

As we know that Intersection means that elements which are common to both the sets.

And it is denoted by '∩'.

So, R∩S={20}

As 20 is the only element that is common in both the sets.

Hence, option 'c' is correct.

Answer 2

The only element both sets have in common is 20
intersection R ∩ S = {20}

C. {20}
