Answer 1

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
