Question

please solve it is urgent.... the digits in the

Answer 1

Given that n=3mn=3m -- ( 1 )

When digits are reversed, number becomes 10m+n10m+n

Orig number - new number = 36

10n+m−(10m+n)=3610n+m−(10m+n)=36
9n−9m=369n−9m=36

Dividing by 4, 

n−m=4n−m=4

Using ( 1 ),

3m−m=43m−m=4

m=2m=2 

Hence n=6

So the original no is 10n+m=10*6+2=62

Answer 2

I hope that this might help you.
