Question

the sum of the digits of a 2 digit number is 10 .the number obtained by interchanging the digits exceeds the original numbed by 36 .find the original number.​

Answer 1

Answer:

Let the unit's digit be x..

Ten's digit = 10-x

Number = 10(10-x) + x

After interchanging digits...

Number = (10x + 10-x) - (100 - 11x) = 36

10x - x - 100 - 11x = 36 - 10

-2x - 100 = 26

-2x = 26 + 100

-2x = 126

x = -63
