hi mate !!

the boy answered 15 answers right

so 15 * 5 ( 5 marks for correct answer so )

=75 keep it aside

the boy got 3 incorrect so

3* -2 ( -2 for wrong answers so )

=-6 keep it aside

the boy didn't attempt 2 questions so

2* -1 ( -1 marks will be removed for unattempted)

=-2

now subtract them from 75

75-6-2

=75-8


=67

so the boy scored 67
