Answer 2

Answer:

Percentage of students absent =25%

Number of students present =45

Be know that total strength of a students are

= 25% absent + 45 present=100%

Percentage of students present= 100- 25

=75

Total strength = 45×100/75=60

Let me verify my answer.

25% absent =60×25/100=15

Number of students present =45

Hence, total strength = 15+45

= 60 students
