Answer 2

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 !
