66 2/3 % of questions are answered correctly and 7 answers were incorrect.Let the number of questions be x.

66 2/3 % of questions= 200/3 % of questions= (200/3*100) *x = 2x/3

2x/3 + 7 = xor, 2x + 21 /3 = xor, 2x + 21 = 3xor, 21 =3x-2xor, 21 = x

Total no. of questions = x =21 questionsAnswers he answered correctly = 2x/3 = 2*21/3 = 42/3 =14 questions
