Let the number of students be x. Then,
Number of students above 8 years of age
=(100−20)%ofx=80%ofx∴80%ofx=48+23of48⇒80100x=80⇒x=100
=(100−20)%ofx=80%ofx∴80%ofx=48+23of48⇒80100x=80⇒x=100
Step-by-step explanation:
No. of students of 8 years of age = 48
No. of students above 8 years of age =
2/3*48 = 32
Let total no. of students be x.
then, (100-20) = 80% of x = 48+32 = 80
Hence, total no. of students = 100
Hope the answer helps you.
