Mike needs 30% to pass. If he scored 212 marks and falls short by 19 marks, what was the maximum marks he could have got?
Choose the correct answer:  A) 543  B) 677  C) 770  D) 867  E) 832

Rationale: "if mike had scored 19 marks more , he could have scored 30 % therefore , mike required 212 + 19 = 231 marks let the maximum marks be m . then 30 % of m = 231 ( 30 / 100 ) × m = 231 m = ( 231 × 100 ) / 30 m = 23100 / 30 m = 770 answer : c"
