If the remainder is 11 when positive integer n is divided by 18, what is the remainder when n is divided by 9? Choose the correct choice from the following answers.
A) 0	B) 2	C) 1	D) 3	E) 4
Assume x is quotient here,   n=18x+11 ----------(1)   and n=9x+ ?   We can also write equation (1) as:   n=(18x+9)+2.   ie 9(2x+1)+2 ie the first term is perfectly divisible by 6.   So,the remainder left is 2.   So,answer (2) is right choice.
