Question 153

Which school has the lowest percentage of students scoring less than 60% marks ?

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)
