When positive integer N is divided by positive integer P, the quotient is 18, with a remainder of 6. When N is divided by (P + 2), the quotient is 15 and the remainder is 3. What is the value of N?
Choices: A) 151 B) 331 C) 168 D) 691 E) 871
N/P=18 6/P= 18P+6   N/(P+2)=15 2/(P+2)=15P+30+3   solving these two equations   we get P=9 N= 168 answer is 168.
