Data Sufficiency from every corner of the globe

QOD2014_128
Explanation
Statement (1) We don’t know whether the organization hired workers from places other than Europe, Asia and Africa. Therefore, statement (1) alone is insufficient. The correct answer would be among B/C/E.

Statement (2) This only tells us that the hired members are from Europe, Asia and Africa. There is no mention about the possible break-up across these locations. Therefore statement (2) alone is also insufficient.

The correct answer would be between C/E.

Statement (1 & 2) Statements (1) and (2) together imply that 100 workers are divided in the ratio 3:1:1 between Europe, Asia and Africa. Let the number of workers in Europe be x.

We get, 3 x + x + x = 100

5x = 100

x = 20

Workers from Europe = 3x = 3(20) = 60

Therefore, both statements together are sufficient.

The correct choice is C.
