1 ​

Answer 1

Step-by-step explanation:

Let the total no. of students in the class be x

Students in hindi class = 1/3 of x

= 1/3×x

= x/3

Students in English class = 1/4 of x

= 1/4×x

= x/4

Students in science class = 1/6 of x

= 1/6×x

= x/6

No. of students in math class = 12

Students in math class = {x-(x/3+x/4+x/6)}

= {x-(4x+3x+2x/12)}

= {x-9x/12}

= {12x-9x/12}

= 3x/12

= x/4

By condition,

x/4 = 12

x = 12×4

x = 48

The total no. of students in the class

is 48.
