Question

answer fastThe digits of a two-digit number differ by 3. If the digits are interchanged, and the resulting number is added to the original number, we get 143. What can be the original number?​

Answer 1

Answer:

Ok, but very sorry I don't know

Answer 2

Step-by-step explanation:

therefore, the two digit numbers is 10× + y and reversed numbe is 10y + ×

Given:

x-y=3----1

Also given

10x+y+×= 143

11× + 11y =143

x+y = 13----2

Adding equation 1 and equation 2

2× = 16

×= 8

therefore, y = x - 3= 8- 3 = 5

Therefore, the two digit number = 10x + y = 10* 8 +5= 85
