Question

There are 14 girls in a class. The number of boys represents 54% of The class. How many total students are in a class

Answer 1

There are 30 students in class

Solution:

Let "x" be the total number of students in class

Given that,

The number of boys represents 54% of the class

Therefore,

Number of boys = 54 % of total number of students

Number of boys = 54 % of x

`\text{Number of boys } = (54)/(100) * x\\\\\text{Number of boys } = 0.54x`

Given that, There are 14 girls in a class

Therefore,

Number of girls = 14

Thus we get,

Number of boys + number of girls = total number of students

0.54x + 14 =x

x - 0.54x = 14

0.46x = 14

Divide both sides by 0.46

`x = 30.43 \approx 30`

Thus there are 30 students in class
