Question

the sum of digits of a 2 digit no. is 13. if the digits are interchanged and the resulting no. is added to the original no. then we get 143. what is the original number

Answer 1

Answer:

I think the info in the question is inadequate because there are multiple answers for this question which are as follows

49 , 58 , 67 , 76 , 85 , 94

Step-by-step explanation:

Assume the number as xy

It would be represented as 10x + y

x + y = 13 (given)

Interchanged number  = 10y + x

Adding both the numbers

10x + y + 10y + x = 143

11(x + y) = 143

x + y = 13

which was given already

Therefore there would be multiple numbers for this question
