If x is the minimum percentage of students who study all three languages and y is the maximum percentage of students who study all three languages, then choose the appropriate values for x and y from the table given below:

For y i.e. maximum, we have at least 70, 75 and 80. Here, the minimum of subsets is 70 so y=70%.
For x, we can get minimum if we assume students studying both subjects as the maximum.
Let, total students=100a. H=70a, F=75a, G=80a.
100a=70a+75a+80a - 100a (assuming maximum) - x
200a-225a=-x or, x=25a i.e. 25%.
x=25, y=70.

Let's say every student studies all three languages (100%). This would match all 3 requirements, however, 100% is larger than the upper bound y = 70. Maybe I misunderstood something here?
