Answer:

Below

Step-by-step explanation:

GiveN :

  • Total marks secured = 320

To finD :

  • Marks secured in each subject

Let the marks that student got in Maths , English , Hindi and Science be x , 2x , 2x and 4x respectively.

Now, Create an equation and solve for x first in order to find the marks that a student secured in Maths.

 \sf{x + 2x + 2x + 4x = 320}

 \longrightarrow{ \sf{9x = 320}}

  \longrightarrow{ \sf{x =  \frac{320}{9} }}

 \longrightarrow{ \sf{x = 35.5}}

 \text{marks \: obtained \: in \: maths = 35.5}

Now, Substitute the value of x :

 \text{marks \: obtained \: in \: english : }\sf{2x = 2  \times 35.5 = 71}

 \text{marks \: obtained \: in \: hindi =  }\sf{ 2x  = 2 \times 35.5  = 71}

 \text{marks \: obtained \: in \: science =  }  \sf{4x = 4 \times 35.5 = 142}

Good Luck !
