Question

In anin an examination in an examination a student scored 4 marks for every correct answer and loses 1 marks for every incorrect answer if you attempt all 75 questions and Secure 125 marks how many questions to attempt correct ​

Answer 1

Answer:

40

Step-by-step explanation:

maximum marks he can score is 75*4=300

125 is less than 50 percent of 300

so the correct answer that he attempted lies in between 40 to 45

check for 40

if he attempted 40 correctly then he can score 40*4=160

but the rest 35 question are wrong so -35

=> 160-35

=125
