He has 20 questions, which leads us to the total marks of the questions asked in test, provided, 10 marks for each right answer, total marks = 20 * 10 = 200
Marks he scored = 125
Marks he lost = 75
Marks deducted for 1 wrong answer = 5
Number of wrong answers if 5 marks are deducted = 1
Number of wrong answer if 1 mark is deducted = 1/5
Number of wrong answers if 75 marks are deducted = 75 * 1/5 = 15
He had 15 wrong answers
