Question

The difference between the digits of a two digit number is 4 if we add this number with the number obtained by interchanging the digits, we get 154 Find the number​

Answer 1

Step-by-step explanation:

Let two digit number =ab=10a+b

Sum of number and reversed number =154

(10a+b)+(10b+a)=154

a+b=14

difference between digits=∣a−b∣=4

a−b=±4

(a+b=14)+(a−b=4)=2a=18 a=9,b=5

(a+b=14)−(a−b−4)=2a=10 a=5,b=9

∴Number=95(or)59
