On a day, there were 27 students present in class six. Sixteen of them were girls, and the rest were boys. If only three boys were absent on that day, represent the information with a mathematical expression and find the number of boys in class six.



Answer :

Let's represent the information given and solve the problem step-by-step.

1. We know the total number of students present in class on that day:
[tex]\[ \text{Total students present} = 27 \][/tex]

2. Out of these, we know the number of girls present:
[tex]\[ \text{Girls present} = 16 \][/tex]

3. To find the number of boys present, we subtract the number of girls present from the total number of students present:
[tex]\[ \text{Boys present} = \text{Total students present} - \text{Girls present} \][/tex]
Substituting the values, we get:
[tex]\[ \text{Boys present} = 27 - 16 = 11 \][/tex]

4. Additionally, we are given that 3 boys were absent on that day.

5. To find the total number of boys in the class, we add the number of boys present and the number of boys absent:
[tex]\[ \text{Total boys} = \text{Boys present} + \text{Boys absent} \][/tex]
Substituting the values, we get:
[tex]\[ \text{Total boys} = 11 + 3 = 14 \][/tex]

Therefore, the number of boys present in class six that day was [tex]\( 11 \)[/tex] and the total number of boys in class six is [tex]\( 14 \)[/tex].
