Answer 1

Answer:

45 marks in science

Step-by-step explanation:

Marks obtained in English = 36

Marks obtained in Hindi = 44

Marks obtained in Maths = 75

Marks obtained in Science = x

Average marks of all subjects = 50

We know that,

Average marks = 50

= 50 × 4 = 155 + x

= x = 200 – 155 = 45.

Hence, Marks in science = 45.

no. of subject=4

and given ave.=50

50=155+x/4

50x4=155+x

200=155+x

x=200-155

x=45
