Answer Show 
Hint: For solving this problem, let x and y be the unit and tens digit of a number respectively. We obtain the first equation by using the sum of digits. Another equation is formed by using the second statement. In this way, we have two variables and two equations, so we can easily obtain the answer.

Are number consists of two digits whose sum is 8 if 18 is added to the number its digits are reversed find the number?∴ the number is 35.
Are twoProduct of numbers is 8. When 18 is subtracted from the number, the digits interchange their places. Since, the digits cannot be in the negative form, hence the value of y = 2. Hence, the required number is 42.
What is the number the sum of two digits is 8?That number is 71. Sum of digits of 71 is 7+1=8 . And if 71 is reversed that is 17 it will be decreased by 54 (71–17=54).
