The difference between two digit number and number obtained by interchangig is 36 what is the difference between sum and difference
Answers
Step-by-step explanation:
Let x and y be two digits of the Numbers.
Such that x is in tens position and y is at the ones place.
So xy is the number,
xy = 10(x) + y(1) ----------> (1).
On interchanging the digits we get,
yx = y(10) + x(1) ----------> (2).
(10x + y) - (10y + x)= 36.
10x + y - 10y - x = 36.
9x - 9y = 36.
x - y = 4.
Answer:
The difference of the digit is x-y =36
Step-by-step explanation:
Let the unit digit be y and tens digit be x,
The required number be 10 x +y
According to the question,
10 x+y - (10 y + x) = 36
or, 9 x-9 y = 36
or, x-y = 4
The difference of the digit is x-y =36
The difference between sum and difference can only be calculated if some more information is provided to make second equation, which will be helpful to find out the value of x and y.
