Correct Question:

A number consits of two digits whose sum is 8.If 18 is added to the number its digits are reserved. Find the number?

$\huge\mathfrak\green{Answer:}$

Given:

• We have been given that a number consists of two digits whose sum is 8.
• When 18 is added to the number, the digits are revesed.

To Find:

• We need to find the number.

Solution:

Let us assume that one number is x.

=> Other number = (8 - x).

Now, by question we have

10x + (8 - x) + 18 = 10(8 - x) + x

= 10x + 8 - x + 18 = 80 - 10x + x

=> 9x + 26 = 80 - 9x

=> 9x + 9x + 26 = 80

= >18x + 26 = 80

=> 18x = 80 - 26

=> 18x = 54

=> x = 3

Therefore, one number is x = 3 and other number is (8 - 3) = 5.

Hence the number formed is 35.
