Question

the sum of the digits of a two digit number is 7. When the digits are reversed, then number is decreased by 9.find the number
​

Answer 1

Let the number be x, x

sum of the digits = 7

x + x + 7 = 9

2x + 7 = 9

2x = 9 - 7

2x = 2

x = 2 / 2

x = 1

After it is decresed,

9 - 1 = 8

Therefore, the final  number is 8
