Explanation

The intersection of two sets X and Y (X ∩ Y) is the set of elements that are common to both X and Y.

Given:

X = {2, 4, 6, 8}

Y = {1, 2, 3, 6}

The common elements are 2 and 6.

So, X ∩ Y = {2, 6}.

Explanation

6 people dig a 200m well in 15 days.

To find the total work done in terms of "man-days":

6 people × 15 days = 90 man-days

Now, let's find the number of people required to dig the same well in 18 days:

Let x be the number of people required.

x people × 18 days = 90 man-days

x = 90 / 18

x = 5

Explanation

The greatest 5-digit number is 99999.

Adding 2 gives 99999 + 2 = 100001, which is 1 more than the smallest 6-digit number (100000).
