When the positive integer x is divided by 11, the quotient is y and the remainder 3. When x is divided by 19, the remainder is also 3. What is the remainder when y is divided by 19?

x=11y+3
x=19k+3
x= 11*19m+3 =11y+3
11y= 19*11m
y=19m

zero is the answer

Suresh, can you please explain how you wrote the following:
x= 11*19m+3 =11y+3

Thanks.

Thanks.

x=11y+3
x=19k+3
--> 11y=19k here y and k are integers
so y must be multiple of 19
and k must be multipe of 11
11y= 11*19m = 19* 11*n
