Question

In a class of 40 students the number who studied French is 10 more than the number who studied History if 8 studied both French and History find using a venn diagram the number who Studied [1] History [2] French only​

Answer 1

11 students studied history

21 students studied French

8 students studied both

Explanation:

first you have to subtract the number of students who studied both classes.

40-8=32

this leaves you with 32 students to study either history or French.

we know 10 more students studied French than history so subtract that from the 32 students because we already know where they go.

32-10=22

we're left with 22 students that can be equally split between the 2 classes.

22/2=11

so there are 11 more students in each history and French.

but don't forget to add the 10 more students that we already knew were in the French class.

11+10=21
