Question

2 In a class 35% of students co irls and the rest one boys . If the total number of Students in the class aire Ho. then find the number of boys in the class.​

Answer 1

Step-by-step explanation:

Total percentage = 100%

if 35% are boys, remaining are girls

So, 100-35 = 65%

= 65% of total students

60 100 = x 160

= 104 girls

Answer 2

Girls = 5/3, Boys =(1− 5/3)= 5/2.

Fraction of students absent = 9/2 of 5/3 + 4/1

of 5/2 = 45/6 + 10/1 = 90/21 = 30/7.

∴ Fraction of students present =(1− 30/7) = 30/23.
