reversed. find the number​

Answer 1

Correct Question:

A number has two digits whose sum is 6. If 18 is added to the reversed number. Find the number.

Step-by-step explanation:

Assume that the ten's digit number be x and one's digit number be y.

As per given condition,

→ x + y = 6

→ x = 6 - y ........................(1)

Original Number = 10x + y and Reversed Number = 10y + x

→ 10y + x + 18 = 10x + y

→ 9x - 9y = 18

→ x - y = 2 ..........................(2)

Substitute value of x in (2)

→ 6 - y - y = 2

→ 2y = 4

→ y = 2

Substitute value of y in x

→ x = 6 - 2

→ x = 4

Hence, the original number is 42 and reversed number is 24.
