Question

a two digit number is 10times the sum of its digit. how many values can it assume? ​

Answer 1

Answer:

9 values can be assumed

Step-by-step explanation:

Let the digit in the tens place be x and units place be y.

Number = 10x + y

Given,

10x + y = 10(x + y)

10x + y = 10x + 10y

9y = 0

y = 0

With y = 0, only 9 two digits can be formed.

10, 20, 30, 40, 50, 60, 70, 80, 90

The given information stands true for all.
