Correct Answer - Option 3 : 64%
Given:
Number of girls = 32
The ratio of girls and Boys = 16 : 9
Concept:
percentage = (part/whole) × 100
Solution:
Let the number = y
Then,
Girls : boys = 16y : 9y
⇒ 16y = 32
⇒ y = 2
Now (put the value of y) boys = 9 × 2 = 18
Total number girls and boys = 32 + 18 = 50
Percentage = (32/50) × 100 = 64%
∴ The % of girls is 64%
