Question

In a two -digit number, the tens digit is 3 times the unit digit. when the digit are reversed, the new number is 36 less than the original number. find the original Number.​

Answer 1

Answer:

original number is 62

Step-by-step explanation:

let tens digit no. be x

and ones digit no be y

given that

x = 3y

also

(10x+y) -(10y+x) =36

solving

9(x-y) =36

x-y = 4

3y-y = 4

y = 2

so x = 6

so no is 62
