1. Answer:

   30 boys

   Step-by-step explanation:

   in a class

   total students =50

   no of girls = 40%

   accordingly,

   no of girls = 40/100×50 = 20

   therefore no of girls =20

   no of boys = total students – girls

   =50 – 20

   = 30 boys

2. In a class there are 50 students.

   Number of girls in the class = 40% of 50 students.

   [tex]no. \: of \: girls = \frac{40}{100} \times 50 \\ \\ = \frac{2000}{100} \\ \\ = 20[/tex]

   No. of boys = Total students – No. of girls

   No. of boys = 50 – 20

   = 30

   So, Total no. of boys in class is 30.
