Answer 1

Explanation:

Given :-

The digits of a 2 digits number differ by 5. If the digits are interchanged and the resulting number is added to the original number we get 99.

To Find :-

What is the original number.

Solution :-

Let, the digits at units place be x

And, the digits at tens place be x + 5

Then, the original number will be 10(x + 5) + x

Now, by interchanging the digits, we get a new number is 10x + (x + 5)

According to the question,

⇒ 10(x + 5) + x + 10x + (x + 5) = 99

⇒ 10x + 50 + x + 10x + x + 5 = 99

⇒ 10x + x + 10x + x + 50 + 5 = 99

⇒ 22x + 55 = 99

⇒ 22x = 99 - 55

⇒ 22x = 44

⇒ x = 44/22

➠ x = 2

Hence, the required digits are,

✧ Unit place = x = 2

✧ Tens place = x + 5 = 2 + 5 = 7

Hence, the required original number is 72

∴ The original number is 72 .
