Let’s check each statement individually-

Statement I-

Only 40% of students were qualified for certain sports events.

It gives only information about percent of candidates is qualified in the sports event.

We cannot find the total number of students using statement I alone.

Statement II-

If 44 more students were qualified, then percentage of students qualified for sports would have been 62%.

It gives the information about qualified students.

But as we don’t know number of total students we cannot find answer for question using statement II alone.

Combining the statements, I and II-

Let the total number of students participating be X.

∴ 40% of students were qualified for certain sports events.

∴ 0.40X students got qualified for sports event. ---- (1)

If 44 more students were qualified, then percentage of students qualified for sports would have been 62%.

∴ 0.4X + 44 = 0.62X

∴ 0.62X – 0.4x = 44

∴ 0.22X = 44

∴ X = 200

∴ Both statements I & II are necessary to find required answer.
