DS - remainders : x divided by 6

by Xbond » Sun Oct 04, 2009 7:51 am
Hi there,

Could you help me to resolve this DS and explain the step of resolution

What is the remainder when the positive integer x is divided by 6 ?

1) When x is divided by 2, the remainder is 1; when x is divided by 3, the remainder is O.

2) when x is divided by 12, the remainder is 3

D

2. We get X = 12C + 3, where C is any positive integer. Since 12 is divisable by 6, answer to the question will always be 3


1. Picking numbers we get odd integers (3, 9, 15..) that satisfy the condition. answer to the question will always be 3 again
