Answer 1

Person City

Cory Santa Clara

Srey Pittsburgh

Molly Des Moines

Mao Seattle

Explanation:

People: Cory, Srey, Molly and Mao

cities: Santa Clara, Seattle, Des Moines, and Pittsburgh

we are given two conditions in the question:

1st condition:

Cory and Molly visited cities with two words in their name

so, the possibilities that Molly and Cory will visit are Santa Clara and Des Moines.

2nd condition:

Mao and Cory visited cities whose names start with an S.

So, the possibilities are Santa Clara and Seattle.

Hence, the possibility that comes in common from both the condition is that Cory will visit Santa Clara.

and then from the first condition Molly will visit Des Moines.

and then from second condition Mao will visit Seattle.

and hence, the last place Pittsburgh will be visited by Srey.

So, we can see from the table:

Person City

Cory Santa Clara

Srey Pittsburgh

Molly Des Moines

Mao Seattle

Answer 2

There are four different cities Santa Clara, Seattle, Des Moines, and Pittsburgh travelled each by 4 people: Cory, Srey, Molly, and Mao. Cory and Molly either visited Santa Clara or Des Moines. Mao and Cory either visited Santa Clara or Seattle. Hence, Cory visted Santa Clara, Molly visited Des Moines, Mao visited Seattle and Srey visited Pittsburgh.
