Question

In a class test, the sum of Moulika's marks in Mathematics and English is 30. If she got 2 marks more in Mathematics and 3 marks less in English, the product of her marks would have been 210. Find her marks in the two
subjects.​

Answer 1

x=12 or x=13

so,marks in maths =12

then,marks in English=30-12=18

and if math=13

then English=30-13=17

Step-by-step explanation:

let her marks in maths be x

then marks in English=30-x

A/q

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

27x-x²+54-2x=210

x²-25x+156=0

x²-12x-13x+156=0

x(x-12)-13(x-12)=0

(x-12) (x-13)=0

x=12orx=13
