Question

Out of 80 students in a class, 16 were absent. What percentage of students was present​

Answer 1

Answer:

Total no of student in a class = 80

No : of student absent = 16

No : of student present = 80 - 16

                                       =  64

Percentage of student present = 64/80 x 100

                                                   =  80%

∴ 80% of students present in the class

Answer 2

→ total number of students in the class = 80

→ number of absent student = 16

→ percentage of present student = ?

$= > 80 - 16 = 64$

→ present student in the class = 64

$= > 100 \times \frac{64}{80} = 16 \times 5 = 80\%$

percentage of present student in the class = 80%
