DS54402.01
Statement One Alone:
Of the 2,500 people in Town X, 1,000 read no newspaper.
Since 1,000 people read no newspaper, we know at least 1,000 people read neither the World newspaper nor the Globe newspaper. However, we can’t determine the exact number of people who read neither one of these two newspapers. For example, say there is a third newspaper called the Earth newspaper and 500 people in the town read only this newspaper; then there are at least 1,500 people who read neither the World newspaper nor the Globe newspaper.
Statement one alone is not sufficient to answer the question.
Statement Two Alone:
Of the people in Town X, 700 read the Globe only and 600 read the World only.
This does not provide us with sufficient information to answer the question since we neither know the number of people who read both newspapers nor do we know the number of different newspapers in town.
Statement two alone is not sufficient to answer the question.
Statements One and Two Together:
Again, since we don’t know the number of different newspapers in town, we can’t answer the question.

Since 1,000 people read no newspaper, we know at most 1,000 people read neither the World newspaper nor the Globe newspaper.
Please let me know ow do you find that at least 1000 people read neither the World newspaper nor the Globe newspaper.
If you add a 3rd newspaper vendor,say X, then if 500 people read only X. Then we can assume that out of 1000 people, there are atleast 500 people wh do not read either the World newspaper or the Global newspaper. Please help me to understand where am I wrong in my understanding
