Answer 2

Answer:

If out of a class of 150 one-third opted for German, two-fifths for Italian, then the rest 40 students opted for French.

Step-by-step explanation:

Given,

Total number of students in the class = 150

One-third of these students opted for German classes.
∴ No. of students who have opted for German are = $(\frac{1}{3} \times 150) = 50$

Again, two-fifths of the students from the whole class, i.e., out of those 150 students opted for Italian classes.
∴ No. of students who have opted for Italian are = $(\frac{2}{5} \times 150) = 60$

∴ No. of students who opted for French classes = 150 - (No. of students who have opted for German classes + No. of students who have opted for Italian classes)

= 150 - (50 + 60)

= 40
