Question

. What should come at the place of question mark if you divide the given number completely by 15? The number is 15457?​

Answer 1

Answer:

15=3×5

So this number should be divisible by both 5 and 3. To be divisible by 5, ? should be either 0 or 5. If you put 0, then the number is not divisible by 3.

So it should be 5.
