Question

In a class of 60 students, the number of girls is one third the number of boys. Find the numberof girls
and boys in the class.
​

Answer 1

Answer:

No .of boys is 45 and girls is 15

Step-by-step explanation:

No. of Students - 60

Number of girls - 1/3 of no. of boys

Let number of boys be = x

=> number of girls = x * 1/3 = x/3

Now, total number of students = number of girls + number of boys

=> 60 = x/3 + x

=> 60 = 4x/3

=> x = (60*3)/4

=> x = 45

Thus, number of boys is 45 and number of girls is 15 (45÷3)

Answer 2

Answer:

Number of total students = 60

Let the number of boys be x

Number of girls = 1/3x

1/3x + x = 60

Taking LCM

1/3x + 3/3x = 60

4/3x = 60

4x = 60×3

4x = 180

x = 180÷4

x = 45

1/3x = 1/3 × 45 = 15

Therefore, Number of boys is 45.

Number of girls is 15.
