Answer:

There are 36 scholars who have a sister.

Step-by-step explanation:

Given that:

Total number of scholars in classes = 90

Fraction of scholars who have a sister = 2/5

Fraction of scholars who have a brother = 1/2

Number of scholars who have sisters = 2/5 of 90

Number of scholars who have sisters = [tex]\frac{2}{5}*90[/tex]

Number of scholars who have sisters = 36

Hence,

There are 36 scholars who have a sisters.
