let she got x marks in mathematics
and marks obtained in english becomes
(30 - x)
now
according to question
if she get 2 more marks in maths
which becomes (x+2)
and 3 marks less in english
which becomes
(30-x-3) = (27-x)
the product becomes 210
so
(x+2)(27-x) = 210
-(x^2) + 25x + 54 = 210
(x^2) - 25x + 156 = 0
x = 12 or 13
so either he got 12 in maths and 18 in english
or 13 in maths and 17 in english
