Question : No. of Paintings = ?

Statement 1: Her next acquisition of 4 Monet paintings will increase the number of paintings in the museum’s collection by 10%.
4 paintings = 10% of total number of painting before including them
i.e total number of painting before including the new 4 paintings = 40
SUFFICIENT

Statement 2: The museum currently exhibits 3 impressionist paintings for every 2 non-impressionist paintings.
This only gives the ratio of two different types of paintings and no absolute value of total number. Hence,
NOT SUFFICIENT

Let the number of paintings in the museum be x

We need to find x..

Statement 1

x + 4 = x + 0.1(x)

4 = 0.1(x)

Sufficient

Statement 2

Impressionist : non-impressionist
3: 2

We don't know anything about the number of each of these paintings . Not enough information
Insufficient

4 represents 10 percent of the paintings. This gives us an actual number (40)
sufficient

(2) The museum currently exhibits 3 impressionist paintings for every 2 non-impressionist paintings.
the ratio does not actually give us an exact number
insufficient

VERITAS PREP OFFICIAL SOLUTION:

Question Type: What Is the Value? This question asks you to provide a specific number of paintings in the museum.

Statement 1: 4 new paintings will increase the number of paintings in the museum by 10%. This can be written as “4 = 0.1x” with x equaling the total number of paintings. Clearly this will be sufficient to provide a specific answer to the question and there is no need to actually solve this equation. This statement is sufficient. The answer will be either A or D.

Statement 2: The ratio of impressionist to non-impressionist paintings is 3:2. This information does not allow you to arrive at a specific number since you do not know either the number of impressionist or the number of non-impressionist paintings. Not sufficient.
