Question

Which two digit numbers when added to 27 get reversed?

Answer 1

Let our number is 10x + y , As x is tens place digit and y is ones .

So, from given condition , we get

10x + y + 27 = 10y + x

9x - 9y = - 27

x - y = - 3

So , here we can have different value of x andy , As :

1 - 4 = -3
their are few more examples ,if you need only one then please avoid all other examples .If you need all the values satisfy this condition then consider all examples
Or

2 - 5 = - 3

Or

3 - 6 = - 3

Or

4 - 7 = - 3

Or

5 - 8 = - 3

Or

6 - 9 = - 3

So, we can have these two digit numbers , As :

we take x = 1 and y 4 , So

14 + 27 = 41

Or

we take x = 2 and y 5, So

25 + 27 = 52

Or

we take x = 3 and y 6 , So

36 + 27 = 63

Or

we take x = 4 and y 7 , So

47 + 27 = 74

Or

we take x = 5 and y 8 , So

58 + 27 = 85

Or

we take x = 6 and y 9 , So

69 + 27 = 96

So,
we can say two digit numbers ( 14 , 25 , 36 , 47 , 58 , 69 ) when added to 27 get reversed.
