A number $$34A$$ is exactly divisible by $$2$$ and leaves a remainder $$1$$, when divided by $$5$$, find $$A$$

If $$345\ A\ 7$$ is divisible by $$3$$,supply the missing digit in place of $$'A'$$

Using divisibility rules , find which of the following numbers are divisible by $$2, 5, 10$$ ( say yes or no ) in the given table . What do you observe?

Number | Divisible by $$2$$ | Divisible by $$5$$ | Divisible by $$10$$ |

$$524$$ | YES | NO | NO |

$$1200$$ | |||

$$535$$ | |||

$$836$$ | |||

$$780$$ | |||

$$3500$$ | |||

$$4820$$ | |||

$$48630$$ |

If another observation $$61$$ is also included to the above data what would be the median?

What is the total number of three digit numbers with unit digit $$7$$ and divisible by $$11$$?
