Question

Let X and Y be the sets of all positive divisors of 400 and 1000 respectively (including 1 and the number). Then, n(X ∩ Y) is equal to

Answer 1

Answer:

it will the set X and Y

Step-by-step explanation:

ad the sets are equal mentioned above ....

so the intersection will also be the same number

Answer 2

n(X ∩ Y) = 12

Given:

Let X and Y be the sets of all positive divisors of 400 and 1000 respectively (including 1 and the number).

To Find:

The value of (X ∩ Y).

Solution:

Consider the :

X and Y as set of all positive divisors between 400 and 1000

Hence,

The intersection of X and Y will be :

n(X ∩ Y) = {1,2,4,5,8,10,20,25,40,50,100,200}

So, n(X ∩ Y) = 12
