Answer 2

Answer:

Let Shefali's marks in math be =x

Given the sum of Shefali's marks in English and Mathematics is 30.

Marks in mathematics + marks in english =30

x + Marks in English =30

Also it is given that ,

she got 2 marks more in Mathematics and 3 marks less in English, the product of their marks would have been 210.

(Marks in Math+2)×(Marks in English -3)=210

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