This is a typical Venn diagram problem. Draw two intersecting circles inside of a rectangle. Labele one circle bikes and the other circle joggers.

Where the circles overlap is whee the people like to do both since anything in that space is in both circles.

That intersecting spade would then be labeled with 16000 people.

This leave inside the circle marked bikes with 33000 - 16000 = 17000 in the remaining portion of the circle which represents bikes only.

The region for joggers only would have 40000 - 16000 = 24000.

So these 3 regions put togethter is 17000 + 16000 + 24000 = 57000.

Your city has 60000 in it and 57000 fit inside the circles and therefore like those activities. This leaves you with 60000 - 57000 = 30000 who don't like either activity.

Hope you could follow the logic.
