Question

In a class, there are 62 students. Number of girls is 2 more than half the number of boys. find the number of girls in the class​

Answer 1

Answer:

         22 girls

Step-by-step explanation:

total number of students = 62

number of boys = x

number of girls = 2 + x/2

x + 2 + x/2 = 62

x + x/2 = 62 - 2

2x + x / 2 = 60

3x/2 = 60

x = 60×2 / 3

x = 20×2

x = 40

number of girls = 2 + x/2 = 2 + 40/2 = 2 + 20 = 22 girls

Answer 2

Answer:

No. of students= 62

Let the number of boys be x

x + 0.5x +2= 62

1.5x + 2= 62

1.5x= 62-2= 60

x= 60 ÷ 1.5= 40

Now we can easily find out the number of girls.

Number of girls= 40/2 + 2= 20+2= 22
