Last year in a group of 30 businesses, 21 reported a net profit and 15 had investments in foreign markets. How many of the businesses did not report a net profit nor invest in foreign markets last year?

(1) Last year 12 of the 30 businesses reported a net profit and had investments in foreign markets.

(2) Last year 24 of the 30 businesses reported a net profit or invested in foreign markets, or both.

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

E. Statements (1) and (2) TOGETHER are NOT sufficient.

I think the answer is D

statement 1: 12 reported a net profit and invested in foreign markets.

businesses reporting a net profit= 21-12=9

businesses invested in foreign market=15-12=3

total businesses reporting net profit, investing in foreign markets or both=12+9+3=24

therefore businesses that did not report a net profit nor invested in foreign market=30-24=6

statement 2 gives the figure 24 which leaves 6 busineses that did not report net profit nor invested in foreign markets.
