Aclass has the same number of girls and boys only eight boys were absent on aparticular day and the number of girls was doublethe number of boys what is the number of boysand girls ?
The ratio of girls to boys in the class is 1:1. Let n be the common multiple. Then:
2(n-8)=n
2n-16=n
n=16
There are 16 boys and 16 girls, normally, in the class. ☺☺☺☺
Maths note class 8 chapter 2
To solve this problem, we can set up an equation based on the given information.
Let's assume the number of boys in the class is 'x'.
According to the given information, the number of girls is double the number of boys, which means the number of girls is 2x.
If there were 8 boys absent, then we can subtract 8 from the total number of boys to get the number of boys present on that day, which is (x - 8).
Now, we can set up an equation by adding the number of boys and girls present:
(x - 8) + 2x = total number of students
Simplifying the equation, we get:
3x - 8 = total number of students
Since the total number of students is not given, we cannot determine the exact number of boys and girls in the class. However, we can express the number of boys and girls in terms of 'total number of students'. The number of boys would be (x - 8), and the number of girls would be 2x.
So, the number of boys in the class would be (x - 8), and the number of girls would be 2x.
