Question

In a class of 30 students 15 know Italian, 10 know French, and 3 know both languages. The rest of the students learn Spanish. How many students learn Spanish?

Answer 1

8 students know Spanish since 12 students know French and 7 students know Italian

Answer 2

8 students learn Spanish.

Explanation:

In a class total number of students are 30.

Students who know Italian = 15

Students who know French = 10

Students who know both = 3

Rest all students know Spanish.

By Venn diagram attached number of students who know Spanish

= [ 30 - (12 + 3 + 7 )]

= 30 - (22)

= 8 students.

8 students learn Spanish.
