1. Answer:

   marks in maths = 12

   marks in marathi = 16

   Step-by-step explanation:

   let marks in maths be x

   marathi marks = 4 + x

   A/Q, 9× marathi marks = (x)^2

   9×(4+x) = x^2

   36+9x = x^ 2

   x^2 – 9x – 36 = 0

   x^2 +3x-12x -36 = 0

   x(x+3) -12 (x+3) =0

   x-12=0. or. x+3 =0 (neglected)

   x= 12

   therefore,. marks in maths = 12

   marathi marks = 12 +4 = 16
