Question

The ten's digit of a two digit number is three times the unit's digit. When the digits are reversed, we get 36 less than the number. Find the original number.

Answer 1

Answer:

62

Step-by-step explanation:

Let say ‘x' is digit on unit's place so 3x is digit on tens' place .

So number is 10*3x+x=31x

Now if reverse the position of digit new number will be

10*x+3x=13x

As given new number is less by 36 from old number

31x-36=13x

18x=36

x=2

So number is 10*3*2+2=62.

Hope this helps you dear!!!
