Solution
The number of students scoring more than 60% marks in school A = $$\frac{55}{100}\times800=440$$
Thus, students scoring exactly 60% marks in school A = $$800-440-320=40$$
Similarly, for other schools :
Clearly, each school but A, has more than half the students scoring less than 60% marks. Thus, school A has the required lowest percentage (400%)
=> Ans - (A)
