Hi,

With the information given in the statement alone, if 'x' is the number of ppl who do all three geographies, we can conclude that

n(Asia alone) = 15 - x
n(Europe alone) = 9 - x
n(NA alone) = 7 - x

n(Asia Union Europe Union NA) = (15 - x) + (9-x) + (7-x) + x + 4 + 6 + 7. Thus, this is an expression involving the term -2x

1. Stmt 1: n(Asia Union Europe Union NA) is given as 38. So, x can be calculated.

2. Stmt 2: This statement does not add any new information. If n(Asia alone) is 15 - x and if n(NA alone) is 7 - x; for all values of x; the former will be greater than the later. Hence, x could be any of the values 0 throgh 7. Not sufficient.

My answer would hence be A.

Hope this helps. Thanks.

Please see the image attached, so we need find the common portion shown in all sets shown as colorless.

Now statement gives us :
(1) The Economic News Weekly has 38 reporters in total covering at least 1 of the following countries: Asia, Europe and North
America

This provides us the total count of reporters

we can have this equation = Total reporters in asia + total reporters in EU + total reporters in N.America - (common reporters in Asia and EU) - (common reporters in Asia and N.America) - (common reporters in EU and N.America) - (total common reporters in all three)

=> 38 = 25+20+20 -6-4-7 -(total common reporters in all three)
=> (total common reporters in all three) = 65 - 17 - 38
=> 10 (statement is suff)

(2) There are more Economic News Weekly reporters covering only Asia than there are Economic News Weekly reporters
covering only North America.

Does not give any specific numbers or numeric relationship so not sufficient.

ANS (A)

Let me know if I have done any step wrong.
