X=243y+98 so X/81 = 243y/81 + 98/81 since 243 is divisible by 81 the remainder of X/81 is remainder of 98/81 that is 17 Therefore subtracting 17 from X will make it divisible by 81 hence A is the answer

Here is my approach => X= 243P+98 for some integer P => X= 81P+98 = 81Q +17 for some integer Q hence if we subtract 17 => X=81Q which would be divisible by P SMASH A Regards Stone Cold
