**Solution:**

Let the marks in Maths be *x*.

Then, the marks in English will be 30 - *x*.

According to the question,

(*x* + 2)(30 - *x* - 3) = 210

(*x* + 2)(27 - *x*) = 210

⇒ -*x*^{2} + 25*x* + 54 = 210

⇒ *x*^{2} - 25*x* + 156 = 0

⇒ *x*^{2} - 12*x* - 13*x* + 156 = 0

⇒ *x*(*x* - 12) -13(*x* - 12) = 0

⇒ (*x* - 12)(*x* - 13) = 0

⇒ *x* = 12, 13

**If the marks in Maths are 12, then marks in English will be 30 - 12 = 18
**

If the marks in Maths are 13, then marks in English will be 30 - 13 = 17
