Answer:56

Step-by-step explanation:

→ Let the digits be x and y.

→ The first number = 10x + y

→ The number obtained after interchanging the digits is = 10y + x

→ According to problem, 10y + x - 10x - y = 9

→ 9y - 9x = 9

→ y - x = 1.....(1)

→ and, y + x = 11.....(2)

→ Adding the equations (1) and (2), we get,

→ 2y = 12

→ y = 6

→ and, x = 5

→ The number is = 56 Ans.
