Answer 1

Answer:

54

-54

Step-by-step explanation:

Two digits are x y

Number = 10x +y

Reversed = 10y + x

(5/6)(10x + y) = 10y + x

50x + 5y = 60y + 6x

44x = 55y

4x = 5y

x = y-1 or y=x-1

x = y-1

4y -4 =5y

y = -4 and x = -5

-54 is number

y = x-1

4x = 5x -5

So x = 5 and y = 4

Number = 54
