Question

State whether the following statement is True or False

If a number is divisible by $9$ and $10$ both, then it must be divisible by $90$.

• A. True
• B. False

Answer 1

The correct option is A True

Checking some numbers which are divisible by $9$ and $10$ both, then they are divisible by $90$ or not:

Lets take some numbers which are divisible by $9$ and $10$ both

For e.g. $\text{90,180,270,360,450,540,630}$ etc.

As we can clearly see all these numbers $\text{90,180,270,360,450,540,630}$ are divisible by $90$ also,

Hence, if a number is divisible by $9$ and $10$ both, then it must be divisible by $90$.

Hence, the given statement is True.
