Question

hey guys,

the sum of the digits in a two-digits number is 10. if 18 is subtracted from the number the result is the number eith the digits reversed. find the digit?

Answer 1

Hey

Here is your answer,

The two digit number = 10x+y

x+y=10

10x+y-18=10y+x
10x - x + y -10y =18
9x -9y =18
Dividing by 9,
x - y =2

Solving both the equation,

X + y =10
X - y =2
_______
2x. =12
X=12/2
X=6

Substitute the value of x in equation to find the value of y,

X+y=10
Y=10-6
Y=4

Two digit number = 10x+y
=10x6+4
=60+4
=64

Hope it helps you!
