Say there are two groups, 5 people in each group. All people in group A earn the same salary X. All people in group B earn the same salary Y (not the same as the people in group A though). Now if I were to form a question trying to find out how much money the people in either group make, how would I phrase it?
1.How much does each person in both groups make?
2.How much does each person in either group make? (Since if i find out how much one person in a group makes, I know how much money everyone in that group makes)
3. How much money do the people in either group make?
4. How much money do the people in both groups make?
Are all these examples grammatically correct? How are they different in terms of meaning?
