Question

If the difference of two digit number and the number obtained by reversing the digits is 117, find the difference between the digits

Answer 1

Answer:

A digit is any one of these symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. For example, the number 23 is written with two digits, 2 and 3. A number is an amount of something. It can be written with one or more – or many – digits.

Answer 2

Answer:

13

Step-by-step explanation:

Let two digit number = ab= 10 a + b

Difference of number and reversed number = 117

(10 a + b) - (10 b + a)=117

10  a + b - 10 b - a = 117

9 a - 9 b = 117

9 (a - b) = 117

∴ a - b = 13.

⇒ The difference between the digits is 13.
