Question

sridevi takes a 2 digit number and subtract it from ​the number obtained by reversing the original number.she also gets the answer 54.how many such numbers are possible

Answer 1

Step-by-step explanation:

Let the 2 digit number be 10x +y

The number obtained by reversing the digits is 10y+x

The (new number obtained — original number)=54

(10y+x) - (10x+y)

9y-9x=54

9(y-x)=54

y-x=6

The possible values of x and y are from 1 to 9

9-3 =6

8-2 =6

7-1 =6

The numbers are 39, 28 and 17

Answer 2

Answer:

Step-by-step explanation:

let the two digit number be X and X+1

T           O

X            X+1

T              O

X+1            X

so after subtracting she gets the answer as 54

X+1 +X ---  X+X+1 = 54

2X + 1  --  2X+1 =54

2X +1 --  2X = 54 -1

0X +1 =53

0X = 53-1

0X=52

X = 52/0

X = 0
