Question

Refer to the survey results shown. Suppose 150 students were surveyed. How many students chose math as their favorite subject

Answer 1

30 Students

Explanation:

Suppose there are a total of 150. If you have 80% adding all the other subjects then 100% - 80% is 20%

20/100 = ?/150 cross multiply

150*20 is 3000

then 3000 divided by 100 is 30
