Question

Who can tell the reason behind this beautiful mathemagic​

Answer 1

Answer:

let the number is 100

so

100×13=1300

1300+7=9100

9100×11=100100 ....

yes ......

Answer 2

$\rule{300}{2}$

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R:-}}}}$

Let us first take 111 as an example since it is a three digit number.

=>111×13=1443

=>1443×7=10101

=>10101×11=111111

Now, let us take 465 as second example

=>465×13=6045

=>6045×7=42315

=>42315×11=465465

• From the above two examples we came to know that by following above given procedure, we get the same number written twice consecutively as our answer.
• It always happens because product of 13, 7 and 11 is 10101 which makes it happens for each three digit number.

This is the best possible answer
