Tom, who has 50 math questions, will get 7 points per question if he chooses a correct answer. If he chooses a wrong answer to a question or skips one, he will lose 2 points per question. Then, which of the following can be the score if he solves all the 50 questions?  Answers:
A) 192  B) 193  C) 194  D) 195  E) 197
Let x be the correctly answered questions. y be the wrongly answered/ skipped ones.   We have x + y = 50;   Score = 7x-2y   2x+2y = 100; 7x-2y = Score;   ==&gt; 9x = 100+Score;   check for answer choices where 100+Score is divisible by 9   Choice (197) 197 fits the equation !
