Answer 2

Answer:

THE ANSWER IS:-

THE STUDENT SCORES "70" MARKS IN MATHEMATICS.

Step-by-step explanation:

WE SOLVE LIKE THIS:-

•MARKS IN LANGUAGE = 65

•MARKS IN SCIENCE = 50

•MARKS IN SOCIAL SCIENCE = 55

•AVERAGE MARKS = 60

THEREFORE,MARKS IN MATHEMATICS = x

•WE KNOW THAT;

55 + 65 + 50 + x/4 = 60

--> 170 + x/4 = 60

--> 170 + x = 240 (60 x 4 = 240)

--> 240 - 170 = 70 = x

SO,MARKS IN MATHEMATICS = 70
