Answer 1

Given : abcde9 *4 = 9abcde

To find :  value of abcde​

Solution :

9 * 4  = 36  =>   e  = 6  and  carry over 3

=> abcd69*4  = 9abcd6

6 * 4  + 3 ( carry over )  = 27   => d  = 7  and  carry over 2

=> abc769 * 4 = 9abc76

7 * 4  + 2  =  30    =>  c =  0      and  carry over 3

=> ab0769 * 4  = 9ab076

0 * 4  + 3  = 3     =>  b  = 3   and no carry over

=> a30769 * 4 = 9a3076

3 * 4  = 12   => a = 2  and  1 carry over

=>  230796 * 4  = 923076

2 * 4 + 1 = 9  ( verified)

230769 * 4  = 923076

abcde9 *4 = 9abcde
