Question

The sum of a two digit number and the number formed by reversing its digit is 77. What are the possible number satisfying this condition?

Answer 1

Answer:

the numbers are 43 and 34,other combinations are 25 and 52,61 and 16

take the digits as x and y.

then original number will be 10y+x

and reversing this number will give you 10x+y

therefore,(10y+x) +(10x+y) =77

solve this equation
