Correct Question:
In a class of 40 students, 40% are girls. Find the number of boys and the number of girls in the class?
Answer:
Let's first find the number of girls ✓
For that we have to convert that percentage of girls into number of girls in the class.
Number of girls in the class = 40% of 40
Now for removing that percentage sign ( % ) we will divide 40% by 100.
As,
➺ 40/100 × 40
➺ 4 × 4
➺ 16
Therefore the number of girls in the class are 16
Now for finding number of boys we will Substract number of girls from the total number of students in the class.
As,
Number of boys = Total number of students - Number of girls
Number of boys = 40 - 16
= 24 boys
So
The number of girls = 16
The number of boys = 24
━━━━━━━━━━━━━━━━━━━━
Now to check whether your answer is correct or not we will add both of them then we will get total number of students in the class.
Total number of students = Number of girls + Number of boys
Total number of students = 16 + 24
= 40 students
Hence Verified!!
