Answer 2

Explanation:

Let the digits of the original number be x and y

Let the digits of the original number be x and yHence, the original number is 10x + y (Assuming x to be the ten's digit and y to be the one's digit)

Let the digits of the original number be x and yHence, the original number is 10x + y (Assuming x to be the ten's digit and y to be the one's digit)After interchanging the digits the new number will be 10y + x (After reversing, y becomes the ten's digit and x becomes the one's digit)

Let the digits of the original number be x and yHence, the original number is 10x + y (Assuming x to be the ten's digit and y to be the one's digit)After interchanging the digits the new number will be 10y + x (After reversing, y becomes the ten's digit and x becomes the one's digit)Condition 1: Sum of the digits is 9 ⇒ x + y = 9     --------- equation (i)

Let the digits of the original number be x and yHence, the original number is 10x + y (Assuming x to be the ten's digit and y to be the one's digit)After interchanging the digits the new number will be 10y + x (After reversing, y becomes the ten's digit and x becomes the one's digit)Condition 1: Sum of the digits is 9 ⇒ x + y = 9     --------- equation (i)Condition 2: The number obtained by interchanging the digits is 27 greater than the earlier number.

Let the digits of the original number be x and yHence, the original number is 10x + y (Assuming x to be the ten's digit and y to be the one's digit)After interchanging the digits the new number will be 10y + x (After reversing, y becomes the ten's digit and x becomes the one's digit)Condition 1: Sum of the digits is 9 ⇒ x + y = 9     --------- equation (i)Condition 2: The number obtained by interchanging the digits is 27 greater than the earlier number.⇒ New number = 27 + original number⇒ 10y + x = 27 + (10x + y)

Let the digits of the original number be x and yHence, the original number is 10x + y (Assuming x to be the ten's digit and y to be the one's digit)After interchanging the digits the new number will be 10y + x (After reversing, y becomes the ten's digit and x becomes the one's digit)Condition 1: Sum of the digits is 9 ⇒ x + y = 9     --------- equation (i)Condition 2: The number obtained by interchanging the digits is 27 greater than the earlier number.⇒ New number = 27 + original number⇒ 10y + x = 27 + (10x + y)⇒ 10y + x = 27 + 10x + y⇒ 10y - y + x - 10x = 27⇒ 9y - 9x = 27
