Let the marks scored by Ravita bemail x. According to the question 9 (x+10)=square of x 9×+90=×^2 ×^2-9×-90=0 (×+6)(×-15)=0 so ×=-6 or 15 X can't be negative so x=15 Ravita got 15 marks.

X=15. 10+15=25. Square of 26 is225. x2-9x-90. Factors x+6=0. x-15=0. Meaningless X=-6. So x=15. 10 added to 15 is 25 (15 square.is 225.)
