Question

the difference of two digit numbers and the number obtained by reversing its digits is 27 what is the difference of sum and difference of the digits if the digits are in the ratio 1:2.​

Answer 1

Answer:

36

Step-by-step explanation:

Answer 2

Answer:

4

Step-by-step explanation:

Let us consider the unit digit be ‘x’

and tens digit be ‘y’

So, the number is =x+10y

By reversing the digits

Unit digit be ‘y’

and tens digit be ‘x’

The number is y+10x=36

Now by equating both numbers,

x+10y–y–10x=36

−9x+9y=36

(y–x)=36/9

y–x=4

∴ The difference between digits of the 2−digit number is y–x=4.
