Question

in class test ,the sum of marks obtained by sachine in maths and science is 28.if he had 2marks more in maths and 2marks less in science the product of his marks is 180.find his marks

Answer 1

Let the marks in maths = x

Marks in science = 28-x

If he obtained 2 marks less in maths = x-2

Same for science = 26-x

product = (x-2)(26-x) = 180

26x -x2 - 52 +2x

28x -52 - x2 = 180

x2 -28x +232 = 0

solve this quadratic and you will get the answer
