Answer:
10
Step-by-step explanation:
Marks given for one correct answer = 5
So, marks given for 10 correct answers
= 5 X 10 = 50
Radhika's score = 30
Marks obtained for incorrect answer
= 30- 50 = -20
Marks given for one incorrect answer
= (-2)
Therefore, number of incorrect answers
= (−20)÷(−2)=10
