Step-by-step explanation:
total 50 questions, correct answer carry 4 marks each and wrong answer negative 2 marks
Radhika
20 × 4 = 80
Rani
25 are wrong means 25 are correct also
so 25 × 4 = 100
and for wrong answers 25 × -2 = -50
so total marks of Rani = 100 - 50 = 50
Hence, radhika scored more by 30 numbers from Rani
