Answer 2

Question :-

A number consists of two digits whose sum is 8. If 18 is added to the

number its digits are reversed. Find the number.

Answer :-

Given :-

• Sum of 2-digit number = 8

• If 18 is added to the number, the digits change their places.

To Find :-

• The Number

Solution :-

• Let one of the number be x

• And the other number be 8 - x

★ According to the question

⇒ 10x + (8 - x) + 18 = 10(8 - x) + x

⇒ 10x + 8 - x + 18 = 80 -10x + x

⇒ 9x + 26 = 80 - 9x

⇒ 9x + 9x = 80 - 26

⇒ 18x = 54

⇒ x = 54/18

⇒ x = 3

• One Number = x = 3

• Other number = 8 - x = 8 - 3 = 5

★ Hence, the number is 35.
