There are 54 customers in an Italian restaurant. There are 9 people who have finished eating. The others are eating pasta or salad or both. There are 34 customers eating pasta and 15 eating salad.How many people are eating just pasta?

• A. 12
• B. 09
• C. 24
• D. 30

Answer 1

The correct option is D

45=34+15-x $\Rightarrow$ x =49-45 =4
thus people eating just pasta =34-4 =30
