Out of 50 children in a class, 20 are boys. Then the percentage of girls is
(a) 60
(b) 30
(c) 50
(d) 66 2/3
Solution:
Given, there are 50 children.
Out of 50, 20 are boys.
We have to find the percentage of girls.
Percentage of girls = (number of girls / total number of children) × 100
Number of girls = total children - number of boys
= 50 - 20
= 30
Percentage of girls = (30/50) × 100
= 3(20)
= 60%
Therefore, the required percentage is 60%
