Let the marks of mathematics be x
Than marks of science be 28-x
now according to question
(x+3),
(28-x-4)
The product of new marks will be 180
So,
(x+3) (28-x-4)=180
24x-x^2+72-3x=180
x^2-21x+108=0
x^2-12x-9x+108=0
x(x-12)-9(x-12)=0
(x-9)(x-12)=0
(x-9)=0 than x=9
(x-12)=0than x=12
If 9 marks got in math than 19 marks got in science
If 12 marks got in math than 16 marks got in science
