Question

The sum of the digit of the number is 10 the number got by reversing the digit is 18 more than the original number

Answer 1

Answer:

Original number = 46

Step-by-step explanation:

Let the digits be x and y.

x + y = 10          ----------> (1)

Original number = 10x + y

Changed number = 10y + x

10x + y + 18 = 10y + x

9x + 18 = 9y

x + 2 = y            ------------> (2)

Substituting 2 in 1,

x + x + 2 = 10

2x = 8

x = 4

y = 6

Original number = 46

Hope this helps! :)
