Sample Problem: A Group Of 40 Students Were Surveyed And Asked…

Sample Problem:

A group of 40 students were surveyed and asked if they like adobo

or sinigang (menu in the canteen). 26 students say they like Adobo,

25 students say they like Sinigang and 14 says they like both dishes.

Questions:

1. How many students like adobo only?

2. How many students like sinigang only?

3. How many students do not like both dishes?

Solution:

Answer:

1. 12 students

2. 11 students

3. 3 students

Step-by-step explanation:

Since there are 14 students who both like adobo and sinigang, you need to subtract the 26 to 14 which is 12. These 12 students only like Adobo.

Then subtract 25 to 14 which is 11. These 11 students only like sinigang.

In order to find out how many student don’t like both dishes, add all the answers which is 12+11+14 is equals to 37. Then 37-40 is equals to 3 students. 3 students don’t like both dishes.
