Answer

To multiply a number with 9 we use the following trick:- The number x(10−1)

13680347×9=(13680347)×(10−1)=136803470−13600347

=123123123

35702369×9=35702369×(10−1)=357023690−35702369

=321321321

25692359×9=25692359(10−1)=256923590−25692359

=231231231

These results repeat the digits 1,2 & 3 in a cyclic pattern.
