Answers

Answered by paru5258

if we devide 3422213 by 99 then the remainder is 75. if we x=2 and y=4, then the whole no. is devided by 99.

charugoyal: ??

paru5258: same, if we devide 3422213 by 99 then the remainder is 80. if we replace xy by19 then the whole no. is devided

charugoyal: bt how do we know that these are the values to be used

paru5258: quient is 3456781

charugoyal: ok

charugoyal: but i still didnt get what r u trying to explain

paru5258: we see the remainder is 80. now see the lest no. 0 put on 80, then the new no. is 800, now we see 99×8 =792 nd the reamaider is 8. now if we put any no. in the plce of y, nvr be remndr is zero. now again we put 1 in the plce of zero then take same process nd see the remainder is 9. now here if we put only 9 in the plce of y, then the no. is devided. if we any other no. then nvr be the remaider is zero

paru5258: ok

charugoyal: kk thanks

paru5258: my eng is not gud, try to understand
