When positive integer N is divided by positive integer P, the quotient is 18, with a remainder of 7. When N is divided by (P + 2), the quotient is 10 and the remainder is 3. What is the value of N?  Choose the correct choice:
A) 151
B) 331
C) 511
D) 43
E) 87
N/P=18 7/P= 18P+7   N/(P+2)=10 1/(P+2)=10P+20+3   solving these two equations   we get P=2 N= 43 answer is 43
