Question

The sum of two digit of a two digit number is 11 .If 63 is added to the number, the digits get reversed. Find the number​

Answer 1

Step-by-step explanation:

suppose two digit no. is 29

by given condition sum is 11

and 29 + 63 = 92

our assumption is correct therefore digits are

2,9

Answer 2

Answer:

Let the digit at unit place be X

Then, the digit at tens place=11-X

Original number=10 (11-X)+1×X

=110-10X+X

=110-9X

Number obtained by reversing its digits=10×X+1(11-X)

=10X+11-X

=9X+11

A/Q

110-9X+63=9X+11

=173-9X=9X+11

=173-11=9x+9x

=162=18X

=162/18=X

=9=X

Original number=110-9X

=110-9×9

=110-81

=29
