Question

If we reverse the digits of the number 12, we get 21. Interestingly, the same is also
true for their squares because the square of 12 is 144 and the square of 21 is 441.
Find another pair of numbers having the same property.
Gind the loact number which is divisible by 12 15 and 18. Also find the smallest​

Answer 1

Here is a better number.

Try 10.

10 reversed is 01 or 1

01 squared reversed is 001 is also 1

Since 12 15 and 18 must be a multiple,

12 * 18 * 15 is the number = 3240

HCF of  12 15 and 18 is 180.

So 180 is smallest number.
