Answer 1

Answer:

The answer is 62.

Step-by-step explanation:

let the digit in the one's place be x

Then, the digit in the tens place = 3x

The no. formed is = 10 x 3x + x= 31x

If the digits are reversed, the new number formed is 10 X x + 3x = 13x

13x = 31x - 36

x = 2

The original no. = 31 X 2 = 62.
