What is the remainder when x is divided by 25?
I. x is a multiple of 5.
II. x is a multiple of 125
We know that if x is a multiple of 5 (factor of 25), it is not necessary that it is divisible by 25 (another multiple of 5) From II, we know that if ‘x’ is a multiple of a number which has 25 as its factor, then x is definitely completely divisible by 25 and thus remainder will be 0.
