Question

those who answered my question first I will Mark you as brainiest ​

Answer 1

let the number of correct answers be x and incorrect be y

therefore in case 1

5x-2y=30 correct answer is 10 then

5(10)-2y =30 therefore y=10

so the no. of wrong questions attempted by radhika is 10

in case 2. the equation is 5x-2y=(-12) and here x<y
